0 =
1 =
Bit 7 and Bit 6 of the CDAxy registers are mapped into the MCDA register.
This can be used for monitoring the D-channel bits on DU and DD and the
“Echo bits” on the TIC bus with the same register.

1 =
Synchronous Transfer Overflow Interrupt
Bit6
The IOM interface is enabled
The IOM interface is disabled (FSC, DCL, clock outputs have high
impedance; DU, DD data line inputs are switched off and outputs
are high impedant)
