MCDA - Monitoring CDA Bits
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.
STI - Synchronous Transfer Interrupt
0 =
1 =
Synchronous Transfer Overflow Interrupt
Enabled STOV interrupts for a certain STIxy interrupt are generated when
the STIxy has not been acknowledged in time via the ACKxy bit in the ASTI
register. This must be one (for DPS = ‘0’) or zero (for DPS = ‘1’) BCL clock
cycles before the time slot which is selected for the STOV.
