Description
Counter Overflow H
This is a status flag indicating that ECH has overflowed.
[Setting condition]
When ECH overflows from H’FF to H’00
[Clearing condition]
When this bit is written to 0 after reading OVH = 1
Counter Overflow L
This is a status flag indicating that ECL has overflowed.
[Setting condition]
When ECL overflows from H'FF to H'00 while CH2 is
set to 1
[Clearing condition]
When this bit is written to 0 after reading OVL = 1
Reserved
Although this bit is readable/writable, only 0 should be
written to.
Channel Select
Selects how ECH and ECL event counters are used
0: ECH and ECL are used together as a single-channel
1: ECH and ECL are used as two-channel 8-bit event
Count-Up Enable H
Enables event clock input to ECH.
0: ECH event clock input is disabled (ECH value is
1: ECH event clock input is enabled
