Value after reset: 00
TIMR
CNT
CNT together with VALUE determine the time period T2 after which a TIN interrupt will
be generated in the normal case:
The timer can be started by setting the STI-bit in CMDR and will be stopped when a TIN
interrupt is generated or the TIMR register is written.
Note: If CNT is set to 7, a TIN interrupt is indefinitely generated after every expiration of
VALUE
T1 = ( VALUE + 1 ) x 0.064 sec
7.1.10
Value after reset: FC
SAP1
SAPI1
Value of the first programmable Service Access Point Identifier (SAPI) according to the
ISDN LAPD protocol.
MHA
0: The SAPI address of an incomming frame is compared with SAP1, SAP2, SAPG
1: The SAPI address of an incomming frame is compared with SAP1 and SAPG.
Data Sheet
SAP1 can be masked with SAP2 thereby bitpositions of SAP1 are not compared
if they are set to ’1’ in SAP2.
