USER-CONFIGURABLE OUTPUTS
There are two user-configurable output pins for each transceiver, OUTA and OUTB. These pins can be
programmed to output various clocks, alarms for line monitoring, or logic 0 and 1 levels to control external circuitry.
They can also be used to access transmit data between the framer and transmit LIU. OUTA and OUTB can be
active low or active high when operating as clock and alarm outputs. OUTA is active high if OUTAC.4 = 1 and
active low if OUTAC.3 = 0. OUTB is active high if OUTBC.4 = 1 and active low if OUTBC.4 = 0 (Table 20-A). Select
mode 0000 to control external circuitry. In this configuration, the OUTA pin follows OUTAC.4 and the OUTB pin
follows OUTBC.4. The OUTAC register also contains a control bit for CMI operation. See Section 22 for details
about CMI operation.

FUNCTION
TTLIE
7
TTL Input Enable. When this bit is set, the receiver can accept TTL
positive and negative data at the RTIP and RRING inputs. The data is
clocked in on the falling edge of MCLK.
CMII
6
CMI Invert. See Section 22 for details.
0 = CMI input data not inverted
1 = CMI input data inverted
CMIE
5
CMI Enable. See Section 22 for details.
0 = CMI disabled
1 = CMI enabled

7
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.
