10.8.4 TOU Control Registers

TOU0 Control Register 0 (TOU0CR0)

<Address: H’0080 07DA>

Bit Name

Function

0, 1

TOU00M0 (TOU0_0 operation mode select 0 bit)

00: Single-shot output mode

2, 3

TOU01M0 (TOU0_1 operation mode select 0 bit)

01: Single-shot PWM output mode

4, 5

TOU02M0 (TOU0_2 operation mode select 0 bit)

or delayed single-shot output mode (Note 1)

6, 7

TOU03M0 (TOU0_3 operation mode select 0 bit)

10: Continuous output mode

8, 9

TOU04M0 (TOU0_4 operation mode select 0 bit)

11: PWM output mode

10, 11

TOU05M0 (TOU0_5 operation mode select 0 bit)

12, 13

TOU06M0 (TOU0_6 operation mode select 0 bit)

14, 15

TOU07M0 (TOU0_7 operation mode select 0 bit)

Note 1: Use TOU0 Control Register 1 to select between these two modes.

Notes: • This register must always be accessed in halfwords.

• Operation mode can only be set or changed while the counter is inactive.

TOU0 Control Register 1 (TOU0CR1)

<Address: H’0080 07D8>

Bit Name

Function

TOU0CKS

0: Use prescaler 3

TOU0 clock source select bit

1: Use external clock (TIN24)

PRS3CKS

0: BCLK/4

Prescaler 3 supplied clock select bit

1: BCLK

2–6

No function assigned. Fix to "0."

0–

TOU0SHEN

0: Disable shorting prevention function

TOU0 shorting prevention function enable bit

1: Enable shorting prevention function

TOU00M1 (TOU0_0 operation mode select 1 bit)

0: Single-shot PWM output mode

TOU01M1 (TOU0_1 operation mode select 1 bit)

1: Delayed single-shot output mode

TOU02M1 (TOU0_2 operation mode select 1 bit)

TOU03M1 (TOU0_3 operation mode select 1 bit)

TOU04M1 (TOU0_4 operation mode select 1 bit)

TOU05M1 (TOU0_5 operation mode select 1 bit)

TOU06M1 (TOU0_6 operation mode select 1 bit)

TOU07M1 (TOU0_7 operation mode select 1 bit)

Notes: • This register must always be accessed in halfwords.

• Operation mode and the short preventiion function can only be set or changed while the counter is inactive.

TOU0 Control Registers 0 and 1 are used to select operation modes of TOU0_0–7.

To select prescaler 3 as the clock source for TOU0, make sure the TID0 Control & Prescaler 3 Enable Register’s

prescaler 3 enable bit is set to "1." For details, see Section 10.7.3, “TID Control & Prescaler Enable Registers.”

Note: • Before setting up or modifying the TOU control register, be sure to stop the relevant timer by

writing "0" to its count enable bit.
