Description

SCC

R/(W)

Synchronous Clearing Control

Specifies whether to clear TCNT_3 and TCNT_4 in the

MTU2S when synchronous counter clearing between

the MTU2 and MTU2S occurs in complementary PWM

mode.

When using this control, place the MTU2S in

complementary PWM mode.

When modifying the SCC bit while the counters are

operating, do not modify the CCE or WRE bits.

Counter clearing synchronized with the MTU2 is

disabled by the SCC bit setting only when synchronous

clearing occurs outside the Tb interval at the trough.

When synchronous clearing occurs in the Tb interval at

the trough including the period immediately after

TCNT_3 and TCNT_4 start operation, TCNT_3 and

TCNT_4 in the MTU2S are cleared.

For the Tb interval at the trough in complementary

PWM mode, see figure 11.40.

In the MTU2, this bit is reserved. It is always read as 0

and the write value should always be 0.

0: Enables clearing of TCNT_3 and TCNT_4 in the

MTU2S by MTU2-MTU2S synchronous clearing

operation

1: Disables clearing of TCNT_3 and TCNT_4 in the

MTU2S by MTU2-MTU2S synchronous clearing

operation

[Setting condition]

• When 1 is written to SCC after reading SCC = 0
