TPnCE bit = 1

Read TPnOPT0 register

(check overflow flag).

TPnCTL0 register

(TPnCKS0 to TPnCKS2 bits)

TPnCTL1 register,

TPnIOC1 register,

TPnOPT0 register

Initial setting of these registers

is performed before setting the

TPnCE bit to 1.

The TPnCKS0 to TPnCKS2 bits can

be set at the same time when counting

has been started (TPnCE bit = 1).

START

Execute instruction to clear

TPnOVF bit (CLR TPnOVF).

<1> Count operation start flow

<2> Overflow flag clear flow

TPnCE bit = 0

Counter is initialized and

counting is stopped by

clearing TPnCE bit to 0.

STOP

<3> Count operation stop flow

TPnOVF bit = 1

YES

Remark n = 0 to 5
