3. Set the TOPCR bit in the TRAIOC register to 0 in modes except for pulse output mode.

X: 0 or 1

NOTE:

1. Pulled up by setting the PU06 bit in the PUR0 register to 1.

NOTE:

1. Set the TOCNT bit in the TRBIOC register to 0 in modes except for programmable waveform generation mode.

X: 0 or 1

NOTES:

1. Pulled up by setting the PU06 bit in the PUR0 register to 1.

2. Set the SSISEL bit in the PMR register to 0 (P3_3).

3. When the SOOS bit is set to 1 (N-channel open drain output) and BIDE bit is set to 0 (standard mode) in the SSMR2 register,

this pin is set to N-channel open drain output.

X: 0 or 1

NOTES:

1. Pulled up by setting the PU07 bit in the PUR0 register to 1.

2. N-channel open drain output by setting the CSOS bit in the SSMR2 register to 1 (N-channel open drain output).
