Bit #
Name
Default
Bit 0: RDEN Invert Enable (RDENI)
Bit 1: RDAT Invert Enable (RDATI)
Bit 2: ROCLK Invert Enable (ROCLKI)
Bit 3: RSOF Invert Enable (RSOFI)
Bit 4: RDAT Force High (RDATH). This bit is set to logic 1 at reset, which puts an all-ones signal on the RDAT
pin. This pin should be cleared once the device has framed to a valid signal. The RDAT pin can be forced low by
setting both the RDATH and RDATI control bits.
Bit 5: RLOS Invert Enable (RLOSI)
Bit 6: ROOF Invert Enable (ROOFI)
Bit 7: Receive Data-Enable Mode Select (RDENMS). When this bit is logic 0, the RDEN/RGCLK output has the
RDEN (data enable) function. RDEN asserts during payload bit times and de-asserts during overhead bit times.
When this bit is logic 1, RDEN/RGCLK has the RGCLK (gapped clock) function. RGCLK pulses during payload bit
times and is suppressed during overhead bit times. See
