Figure 9-5. Flowchart of Basic Operation for Batch Write

START

Initial settings

• Set values to TT0CCRn register

• Timer operation enable (TT0CE

bit = 1)

→ Transfer values of TT0CCRn

Timer operation

• Match between 16-bit counter

and CCR1 buffer register

Note

• Match between 16-bit counter

and CCR0 buffer register

• 16-bit counter clear & start

• Transfer of values of TT0CCRn

INTTT0CC1 signal output

TT0CCR0 register rewrite

TT0CCR1 register rewrite

INTTT0CC0 signal output

Batch write enable

Note The 16-bit counter is not cleared upon a match between the 16-bit counter value and the CCR1

buffer register value. It is cleared upon a match between the 16-bit counter value and the CCR0

buffer register value.

Caution Writing to the TT0CCR1 register includes enabling of batch write. Thus, rewrite the

TT0CCR1 register after rewriting the TT0CCR0 register.

Remark The above flowchart illustrates an example of the operation in the PWM output mode.
