ALVVB
Specifies the output level of the TO0n3 pin.
0: Inverted level of active level set by ALVTO bit
1: Active level set by ALVTO bit
When the ALVVB bit = 1, the output level of the TO0n3 output is the same as
TO0n2.
Caution Changing the ALVVB bit during TM0n operation (TM0CEn = 1) is
prohibited.
4
ALVWB
Specifies the output level of the TO0n5 pin.
0: Inverted level of active level set by ALVTO bit
1: Active level set by ALVTO bit
When the ALVWB bit = 1, the output level of the TO0n5 output is the same as
TO0n4.
Caution Changing the ALVWB bit during TM0n operation (TM0CEn = 1) is
prohibited.
3
TOSP
Controls TO0n0 to TO0n5 pin output stop through ESOn pin input.
0: Enables ESOn pin input
1: Disables ESOn pin input
Cautions 1. The output stop status can be released by writing “1” to the
TORSn bit of the TUC0n register. The operation continues
even if output is prohibited for all timers and counters.
2. Before changing the ESOn pin input status from disable to enable
(changing TOSP bit from 1 to 0), write “1” to the TORSn bit of the
TUC0n register to reset the ESOn pin input status.
These bits select the valid edge or level when setting forcible stop of TO0n0 to
TO0n5 output through ESOn pin input with the TOSP bit.

Cautions 1.
Changing the TOEDG1, TOEDG0 bits during TM0n operation
(TM0CEn = 1) is prohibited.
2. Before changing the settings of bits TOEDG1 and TOEDG0,
write “1” to the TORSn bit of the TUC0n register to reset the ESOn
pin input status.
