AFI3FAIL
AFI2FAIL
AFI1FAIL
AFI0FAIL
The bits CUFAIL, AFI3FAIL, AFI2FAIL,AFI1FAIL and AFI0FAIL are read only.
5.1.3
All Write Registers are Write Only Registers and cannot be read out.
CTRLTSMON[6:0] (Addr.: 2FH): Control of TS to be monitored, Reset value = 00H
SNAPSHOT
MVAL
MCH[4:0]
If MVAL = '1' the Monitor Read Registers are filled with the values of timeslot MCH[4:0]
as soon as this timeslot is processed. The availibility of the monitored values in the
Monitor Read Registers is indicated by setting the bit IRREQ.TSM and STATUS.TSM.
