Error Counter Mode
The function of the error counters is determined by this bit.
0
1 =
0 =
1 =
Transmit AIS towards Remote End
0 =
1 =
Enable CMI Transmit Interface
Before reading an error counter, the corresponding bit in the
command register (CMDR) has to be set. The low byte of the
error counter should always be read before the high byte. The
error counter is reset with the rising edge of the corresponding
bits (DBEC, DCVC) in the CMDR register.
Every second the error counter is latched and then reset
automatically. The latched error counter state must be read
within the next second, otherwise data is overwritten. Avoid
reading the error counter during updating.
The ternary interface is selected. XL1/2 are used as analog
outputs.
The digital CMI receive interface is selected. Transmitted data
is output on port XOID.
Normal transmit operation.
Sends AIS via ports XL1/XL2 towards the remote end. The
outgoing data stream which can be looped back via the local
loop to the framer interface is not affected.
