SRDY enable. If SSI_RDYEN and SSI_EN are high, the SEG6 pin is
configured as SRDY. Otherwise, it is an LCD driver.
SRDY polarity: 0: positive, 1: negative
The beginning and ending address of the transfer region of the CE
data memory. If the SSI is enabled, a block of words starting with
SSI_BEG and ending with SSI_END will be sent. SSI_END must be
larger than SSI_BEG. The maximum number of output words is limited
by the number of SSI clocks in a CE code pass—see FIR_LEN,
MUX_DIV, and SSI_10M.
Together w/ PRE_SAMPS, this value determines (for the CE) the
number of samples in one sum cycle between XFER interrupts.
Number of samples = PRE_SAMPS*SUM_CYCLES.
Selects one of 16 inputs for TMUXOUT.
0 – DGND (analog)
1 – IBIAS (analog)
2 – PLL_2.5V (analog)
3 – VBIAS (analog)
4 – RTM (Real time output from CE)
5 – WDTR_EN (Comparator 1 Output AND V1LT3)
6 – reserved
7 – reserved
8 – RXD (from Optical interface)
9 – MUX_SYNC (from MUX_CTRL)
A – CK_10M
B – CK_MPU
C – reserved for production test
D – RTCLK
E – CE_BUSY
F – XFER_BUSY
Must be zero.
Selects the temperature trim fuse to be read with the TRIM register
(TRIMM[2:0]: 4, TRIMBGA: 5, TRIMBGB: 6)
Contains TRIMBGA, TRIMBGB, or TRIMM[2:0] depending on the
value written to TRIMSEL. If TRIMBGB = 0 then the IC is a 6511 else
the IC is a 6511H.
The silicon revision number. This data sheet does not apply to
revisions < 000 0100.
Brings VREF out to the VREF pin. This feature is disabled when
VREF_DIS=1.
Disables the internal voltage reference.
Resets the WD timer. The WDT is reset when a 1 is written to this bit.
Only byte operations on the whole WDI register should be used.
The WD overflow status bit. This bit is set when the WD timer
overflows. It is powered by the VBAT pin and at boot-up will indicate if
the part is recovering from a WD overflow or a power fault. This bit
should be cleared by the MPU on boot-up. It is also automatically
cleared when RESETZ is low.
