NAME AND DESCRIPTION
NRZ Enable.
When this bit is set, the receiver can accept TTL type
NRZ data at the RTIP input. RRING becomes a clock input.
0 = RTIP and RRING are in normal mode
1 = RTIP becomes an NRZ TTL type input and RRING is its
associated clock input. Data at RTIP is clocked in on the falling edge of
the clock present on RRING.
Unused.
Should Be set = 0 for proper operation
Unused.
Should Be set = 0 for proper operation
OUTB control bit 4.
Inverts OUTB output
OUTB control bit 3.
See Table 18-1 for details
OUTB control bit 2.
See Table 18-1 for details
OUTB control bit 1.
