Event Dividing Counters 0–3 (EVDV0–EVDV3)
EVDV0–EVDV3 are 6-bit counters that count the valid edge (specified by CAPCON)
input to CAP0–CAP3 pins for the value specified by EVNTCONL and EVNTCONH.
Figure 11-11 shows the configuration of EVDVn (n = 0–3).
Figure 11-11 Configuration of EVDVn (n = 0–3)
Whatever data is written to EVDV0–EVDV3, the counter is cleared to "0". Read is valid,
but "1" is read from the high-order 2 bits. EVDV0–EVDV3 are cleared to "0" when a
capture event is generated.
At reset (when the
RES
signal is input, the BRK instruction is executed, a watchdog
timer is overflown, or an operation code trap is generated), EVDV0–EVDV3 become
C0H.

EVDV0–EVDV3 Buffer Registers (EVDV0BF–EVDV3BF)
EVDV0BF–EVDV3BF are 6-bit registers that hold the content of EVDV0–EVDV3
(content just prior to being cleared to "0") when a capture event is generated.
Figure 11-12 shows the configuration of EVDVnBF (n = 0–3).
Figure 11-12 Configuration of EVDVnBF (n = 0–3)
Write to EVDV0BF–EVDV3BF is valid, however write to the high-order 2-bits is invalid.
Read is valid, however "1" is read from the high-order 2-bits.
If the content of EVNTCONL or EVNTCONH is updated and the dividing ratio is
changed during a capture operation, it is necessary to check whether an interrupt was
generated based on normal dividing, by testing the content of EVDVnBF at the begin-
ning of the capture interrupt process program.
At reset (when the
RES
signal is input, the BRK instruction is executed, the watchdog
timer is overflown, or an operation code trap is generated), EVDV0BF–EVDV3BF
become C0H.
