TIMR1
SAP1
ITF… Interframe Time Fill
Selects the inter-frame time fill signal which is transmitted between HDLC-frames.
0 … idle (continuous ’1’)
1 … flags (sequence of patterns: ‘0111 1110’)
Note: ITF must be set to ’0’ for power down mode.
4.1.9
Value after reset: 00
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
Data Sheet
In applications with D-channel access handling (collision resolution), the only
possible inter-frame time fill is idle (continuous ’1’). Otherwise the D-channel on
the S/T-bus cannot be accessed
T1 (i.e. T = T1).
