Value after reset: 00
TIMR1
CNT ... Timer Counter
CNT together with VALUE determines the time period T after which a AUXI.TIN1
interrupt will be generated:
CNT=0...6:T = CNT x 2.048 sec + T1
CNT=7:T = T1 = ( VALUE+1 ) x 0.064 sec
The timer can be started by setting the STI-bit in CMDRD and will be stopped when a
TIN1 interrupt is generated or the TIMR1 register is written.
Note: If CNT is set to 7, a TIN interrupt is indefinitely generated after every expiration of
VALUE ... Timer Value
Determines the value of the timer value T1 = ( VALUE + 1 ) x 0.064 sec.
4.1.10
Value after reset: FC
SAP1
SAPI1 ... SAPI1 value
Value of the first programmable Service Access Point Identifier (SAPI) according to the
ISDN LAPD protocol.
MHA... Mask High Address
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 bit positions of SAP1 are not compared
if they are set to ’1’ in SAP2.
