10.5.12 Line Interface Modes
The line interface modes can be selected semi-independently of the framing modes using the PORT.CR2.LM
control bit. The major block enabled is the line encoder/decoder block. The line encoder/decoder is used for B3ZS,
HDB3 and AMI line interface encoding modes. The line encoder/decoder block is not used for line encoding or
decoding in the UNI mode but the BPV counter in it can be used to count external pulses on the RNEGn / RCLVn /
ROHMn pin. In “OHM” modes, the line encoder-decoder does not count pulses on the RNEGn / RLCVn / ROHMn
pin.
The line codes are determined by the framing mode and the TZCDS and RZCDS bits, which control the AMI line
mode selection bits in the line encoder/decoder blocks. The DS3 and CC52 framing modes select the B3ZS line
coding, the E3 framing modes select the HDB3 line codes. Refer to
