Bit 0: RDEN Invert Enable (RDENI)
0 = do not invert the RDEN signal (normal mode)
1 = invert the RDEN signal (inverted mode)
Bit 1: RDAT Invert Enable (RDATI)
0 = do not invert the RDAT signal (normal mode)
1 = invert the RDAT signal (inverted mode)
Bit 2: ROCLK Invert Enable (ROCLKI)
0 = do not invert the ROCLK signal (normal mode)
1 = invert the ROCLK signal (inverted mode)
Bit 3: RSOF Invert Enable (RSOFI)
0 = do not invert the RSOF signal (normal mode)
1 = invert the RSOF signal (inverted mode)
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.
0 = do not force RDAT high (normal mode)
1 = force RDAT high (default reset mode)
Bit 5: RLOS Invert Enable (RLOSI)
0 = do not invert the RLOS signal (normal mode)
1 = invert the RLOS signal (inverted mode)
Bit 6: ROOF Invert Enable (ROOFI)
0 = do not invert the ROOF signal (normal mode)
1 = invert the ROOF signal (inverted mode)
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 Figure 5-2 for timing information.
0 = RDEN (data enable) mode
1 = RGCLK (gapped clock) mode
