<2>: Enable Synchronization from SYNC2 Bit. Similar to
Bit <3> for the SYNC2 pin.
<1>: Enable Synchronization from SYNC1 Bit. Similar to
Bit <3> for the SYNC1 pin.
<0>: Enable Synchronization from SYNC0 Bit. Similar to
Bit <3> for the SYNC0 pin.
Soft Synchronization Configuration <7:0>
<7>: Soft Hop Synchronization Enable Bit. When this bit is set,
hop synchronization is enabled for all channels selected using
Bit 5 through Bit 0. When this bit is cleared, hop synchroniza-
tion is not performed for any channels selected using Bit 5 to
Bit 0.
<6>: Soft Start Synchronization Enable Bit. When this bit is set,
start synchronization is enabled for all channels selected using
Bit 5 through Bit 0. When this bit is cleared, start synchronization
is not performed for any channels selected using Bit 5 to Bit 0.
Bits <5:0> form the SOFT_SYNC control bits. These bits can be
written to by the controller to initiate the synchronization of a
selected channel.
<5>: Soft Sync Channel 5 Enable Bit. When this bit is set, it
enables Channel 5 to receive a hop sync or start sync, as defined
by Bit 7 and Bit 6, respectively. When cleared, Channel 5 does
not receive any soft sync.
<4>: Soft Sync Channel 4 Enable Bit. Similar to Bit <5> for
Channel 4.
<3>: Soft Sync Channel 3 Enable Bit. Similar to Bit <5> for
Channel 3.
<2>: Soft Sync Channel 2 Enable Bit. Similar to Bit <5> for
Channel 2.
<1>: Soft Sync Channel 1 Enable Bit. Similar to Bit <5> for
Channel 1.
<0>: Soft Sync Channel 0 Enable Bit. Similar to Bit <5> for
Channel 0.
<10:9>: Reserved. This bit must be written with Logic 1.
<8:0>: Reserved. This bit must be written with Logic 0.
Interrupt Status Register <15:0>
This register is read only.
<15>: AGC5 RSSI Update Interrupt Bit. If the AGC5 update
interrupt enable bit is set, this bit is set by the AD6654
whenever AGC5 updates a new RSSI word (the new word
should be different from the previous word). If the AGC5
<10:0>: Reserved.

update interrupt enable bit is cleared, then this bit is not set (not
updated). An interrupt is not generated in this case.
Note: For Bits <15:10>, no interrupt is generated, if the new
RSSI word is the same as the previous RSSI word.
<14>: AGC4 RSSI Update Interrupt Bit. Similar to Bit <15> for
the AGC4.
<13>: AGC3 RSSI Update Interrupt Bit. Similar to Bit <15> for
the AGC3.
<12>: AGC2 RSSI Update Interrupt Bit. Similar to Bit <15> for
the AGC2.
<11>: AGC1 RSSI Update Interrupt Bit. Similar to Bit <15> for
the AGC1.
<10>: AGC0 RSSI Update Interrupt Bit. Similar to Bit <15> for
the AGC0.
<9>: Channel 5 Data Ready Interrupt Bit. This bit is set to
Logic 1 whenever the channel BIST signature registers are
loaded with data. The conditions required for setting this bit are
that the channel BIST signature registers are programmed for
BIST signature generation and the Channel 5 data ready enable
bit in the interrupt enable register is cleared. If the Channel 5
data ready enable bit in the interrupt enable register is set, the
AD6654 does not set this bit on signature generation and an
interrupt is not generated.
<8>: Channel 4 Data Ready Interrupt Bit. Similar to Bit <9> for
Channel 4.
<7>: Channel 3 Data Ready Interrupt Bit. Similar to Bit <9> for
Channel 3.
<6>: Channel 2 Data Ready Interrupt Bit. Similar to Bit <9> for
Channel 2.
<5>: Channel 1 Data Ready Interrupt Bit. Similar to Bit <9> for
Channel 1.
<4>: Channel 0 Data Ready Interrupt Bit. Similar to Bit <9> for
Channel 0.
<3>: Reserved. This bit must be written with Logic 0.
<2>: ADC Port Power Monitoring Interrupt Bit. This bit is set
by the AD6654 whenever the ADC port power monitor
interrupt enable bit is set and the ADC port power monitor
timer runs out (end of the ADC port power monitor period). If
the ADC port power monitor interrupt enable bit is cleared, the
AD6654 does not set this bit and does not generate an interrupt.
<1>: Reserved. This bit must be written with Logic 0.
<0>: Reserved. This bit must be written with Logic 0.
