Clock Select Inputs for Master Clock Synthesizer bit 2:
In Host mode, CLKSEL[2:0] are input signals to a programma-
ble frequency synthesizer that can be used to generate a mas-
ter clock from an external accurate clock source according to
the following table;
In Hardware mode, the state of these signals are ignored and
the master frequency PLL is controlled by the corresponding
Hardware pins.
Clock Select inputs for Master Clock Synthesizer bit 1:
Clock Select inputs for Master Clock Synthesizer bit 0:
Master Clock Synthesizer to generate the T1/J1 or E1 clock.
The Master Clock Synthesizer will generate the E1 clock when
MCLKRATE = “0”, and the T1/J1 clock when MCLKRATE =
“1”.
Receive Output Mute: Writing a “1” to this bit, mutes receive
outputs at RPOS/RDATA and RNEG/LCV pins to a “0” state for
any channel that detects an RLOS condition.
