TCORA0 to TCORA3 are 8-bit readable/writable registers. The TCORA0 and TCORA1 pair, and
the TCORA2 and TCORA3 pair, can each be accessed as a 16-bit register by word access.
The TCORA value is constantly compared with the 8TCNT value. When a match is detected, the
corresponding compare match flag A (CMFA) is set to 1 in 8TCSR.
The timer output can be freely controlled by these compare match signals and the settings of
output select bits 1 and 0 (OS1, OS0) in 8TCSR.
Each TCORA register is initialized to H'FF by a reset and in standby mode.
