10.7.18 Cautions on Transition from Normal Operation or PWM Mode 1 to Reset-
Synchronous PWM Mode
When making a transition from channel 3 or 4 normal operation or PWM mode 1 to reset-
synchronous PWM mode, if the counter is halted with the output pins (TIOC3B, TIOC3D,
TIOC4A, TIOC4C, TIOC4B, TIOC4D) in the high-impedance state, followed by the transition to
reset-synchronous PWM mode and operation in that mode, the initial pin output will not be
correct.
When making a transition from normal operation to reset-synchronous PWM mode, write H'11 to
registers TIORH_3, TIORL_3, TIORH_4, and TIORL_4 to initialize the output pins to low level
output, then set an initial register value of H'00 before making the mode transition.
When making a transition from PWM mode 1 to reset-synchronous PWM mode, first switch to
normal operation, then initialize the output pins to low level output and set an initial register value
of H'00 before making the transition to reset-synchronous PWM mode.
10.7.19 Output Level in Complementary PWM Mode and Reset-Synchronous PWM Mode
When channels 3 and 4 are in complementary PWM mode or reset-synchronous PWM mode, the
PWM waveform output level is set with the OLSP and OLSN bits in the timer output control
register (TOCR). In the case of complementary PWM mode or reset-synchronous PWM mode,
TIOR should be set to H'00.
10.7.20 Interrupts in Module Standby Mode
If module standby mode is entered when an interrupt has been requested, it will not be possible to
clear the CPU interrupt source or the DTC activation source. Interrupts should therefore be
disabled before entering module standby mode.
10.7.21 Simultaneous Input Capture of TCNT-1 and TCNT-2 in Cascade Connection
When cascade-connected timer counters (TCNT-1 and TCNT-2) are operated, cascade values
cannot be captured even if input capture is executed simultaneously with TIOC1A or TIOC1B and
TIOC2A or TIOC2B.
