TIDR: TRANSMIT IDLE DEFINITION REGISTER (Address = 2A Hex)
9.1.2 Per-Channel Code Insertion
The second method involves using the Transmit Channel Control Registers (TCC1/2/3/4) to determine
which of the 32 E1 channels should be overwritten with the code placed in the Transmit Channel
Registers (TC1 to TC32). This method is more flexible than the first in that it allows a different 8-bit code
to be placed into each of the 32 E1 channels.
TC1 TO TC32: TRANSMIT CHANNEL REGISTERS (Address = 60 to 7F Hex)
(For brevity, only channel 1 is shown; see
