Section 12 Timer V
12.3.2
TCORA and TCORB have the same function.
TCORA and TCORB are 8-bit read/write registers.
TCORA and TCNTV are compared at all times. When the TCORA and TCNTV contents match,
CMFA is set to 1 in TCSRV. If CMIEA is also set to 1 in TCRV0, a CPU interrupt is requested.
Note that they must not be compared during the T3 state of a TCORA write cycle.
Timer output from the TMOV pin can be controlled by the identifying signal (compare match A)
and the settings of bits OS3 to OS0 in TCSRV.
TCORA and TCORB are initialized to H'FF.
12.3.3
TCRV0 selects the input clock signals of TCNTV, specifies the clearing conditions of TCNTV,
and controls each interrupt request.

Description
Compare Match Interrupt Enable B
When this bit is set to 1, interrupt request from the CMFB
bit in TCSRV is enabled.
Compare Match Interrupt Enable A
When this bit is set to 1, interrupt request from the CMFA
bit in TCSRV is enabled.
Timer Overflow Interrupt Enable
When this bit is set to 1, interrupt request from the OVF
bit in TCSRV is enabled.
Counter Clear 1 and 0
These bits specify the clearing conditions of TCNTV.
00: Clearing is disabled
01: Cleared by compare match A
10: Cleared by compare match B
11: Cleared on the rising edge of the TMRIV pin. The
operation of TCNTV after clearing depends on TRGE
in TCRV1.
