Semiconductor Group
4.2.6.2 Timer Register (TIMR)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
Reset value: 00
The EPIC timer can be used for 3 different purposes: timer interrupt generation
(ISTA:TIG), FSC multiframe generation (CMD2:FC2..0 = 111) and last look period
generation.
SSR
TVAL6..0 Timer Value bits 6..0; the timer period, equal to (1+TVAL6..0)
The timer is started as soon as CMDR:ST is set to 1 and stopped by writing the TIMR
register or by selecting OMDR:OMS0 = 0.
bit 7

Signaling Sampling Rate.
0… the last look period is defined by TVAL6..0.
1… the last look period is fixed to 125 s.
programmed here. It can thus be adjusted within the range of 250 s up to
32 ms.
