13.3.2
Time Constant Register A (TCORA)
TCORA is an 8-bit readable/writable register. TCORA_0 and TCORA_1 (or TCORA_X and
TCORA_Y) comprise a single 16-bit register, so they can be accessed together by word access.
TCORA is continually compared with the value in TCNT. When a match is detected, the
corresponding compare-match flag A (CMFA) in TCSR is set to 1. Note however that comparison
is disabled during the T
2
state of a TCORA write cycle. The timer output from the TMO pin can be
freely controlled by these compare-match A signals and the settings of output select bits OS1 and
OS0 in TCSR. TCORA is initialized to H'FF.
13.3.3
Time Constant Register B (TCORB)
TCORB is an 8-bit readable/writable register. TCORB_0 and TCORB_1 (or TCORB_X and
TCORB_Y) comprise a single 16-bit register, so they can be accessed together by word access.
TCORB is continually compared with the value in TCNT. When a match is detected, the
corresponding compare-match flag B (CMFB) in TCSR is set to 1. Note however that comparison
is disabled during the T
2
state of a TCORB write cycle. The timer output from the TMO pin can be
freely controlled by these compare-match B signals and the settings of output select bits OS3 and
OS2 in TCSR. TCORB is initialized to H'FF.
