• Low level is output from the TOT01 pin when the TT0OL1 bit = 0.
• High level is output from the TOT01 pin when the TT0OL1 bit = 1.

Note The output level of the timer output pins (TOT00 and TOT01) specified by the
TT0OLn bit is shown below (n = 0, 1).

TT0CE bit
TOT0n pin output
16-bit counter
• When TT0OLn bit = 0 • When TT0OLn bit = 1
Cautions 1. If the setting of the TT0IOC0 register is changed when TOT00 and
TOT01 outputs are set for the port mode, the output of the pins
change. Set the port in the input mode and make the port go into a
high-impedance state, noting changes in the pin status.
2. Rewrite the TT0OL1, TT0OE1, TT0OL0, and TT0OE0 bits when the
TT0CTL0.TT0CE bit = 0. (The same value can be written when the
TT0CE bit = 1.) If rewriting was mistakenly performed, clear the
TT0CE bit to 0 and then set the bits again.
3. Even if the TT0OL0 or TT0OL1 bit is manipulated when the TT0CE,
TT0OE0, and TT0OE1 bits are 0, the output level of the TOT00 and
TOT01 pins changes.
