11.3.2 Time Constant Registers A and B (TCORA, TCORB)
TCORA and TCORB have the same function.
TCORA and TCORB are 8-bit readable/writable registers. TCORA and TCNTV are compared at
all times. When the TCORA and TCNTV contents match, the CMFA flag in TCSRV is set to 1. If
the CMIEA bit in TCRV0 is also set to 1, 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 the OS3 to OS0 bits in
TCSRV.
TCORA and TCORB are initialized to H'FF.
