Basic PC Operation and I/O Processes Section 1-2
CPM1/CPM1A PCs Set the input time constants for CPM1/CPM1A inputs from a Peripheral
Device.
Input Time Constants for IR 000
Input Time Constants for IR 001 to IR 009
The nine possible settings for the input time constant are shown below. Set
only the rightmost digit for IR 000.
0: 8 ms 1: 1 ms 2: 2 ms 3: 4 ms 4: 8 ms
5: 16 ms 6: 32 ms 7: 64 ms 8: 128 ms
The CPM1/CPM1A’s I/O response time is the input time constant (1 ms to
128 ms; default is 8 ms) + the cycle time.
Refer to 7-2 CPM1/CPM1A Cycle Time and I/O Response Time for more
details.
1-2-8 High-speed Timers (CQM1 Only)
Make the settings shown below to set the number of high-speed timers cre-
ated with TIMH(15) that will use interrupt processing.
The setting indicates the number of timers that will use interrupt processing
beginning with TIM 000. For example, if “0108” is specified, then eight timers,
TIM 000 to TIM 007 will use interrupt processing.
Note High-speed timers will not be accurate without interrupt processing unless the
cycle time is 10 ms or less.
