Setting of Programmable Waveform Generation Mode

Figures 1.13.10 and 1.13.11 show the setting of the programmable waveform generation mode.

Figure 1.13.10 Setting of Programmable Waveform Generation Mode (1)

Timer 1 count source selection

00: f(XIN)/8

01: f(XIN)/64

10: f(XIN)/128

11: f(XIN)/256

Procedure 1 Stop of timer count

Notes 2 : Procedure 1 and 3 can be set simultaneously

because the described register is the same.

Programmable waveform generation mode

Timer 1 mode register (T1M) [Address 00F916]

Procedure 3 Setting timer mode register

Timer 1 mode register (T1M) [Address 00F916]

• when timer 1 is used

Timer 1 count is stopped.

• when timer 2 is used

Timer 2 mode register (T2M) [Address 00FA16]

Timer 2 count is stopped.

• when timer 1 is used

• when timer 2 is used

Timer 2 count source selection

00: f(XIN)/8

01: f(XIN)/64

10: f(XIN)/128

11: f(XIN)/256

Programmable waveform generation mode

Timer 2 mode register (T2M) [Address 00FA16]

Procedure 2 Setting port which is also used as T pin to output mode (Note 1)

Port P1 direction register (P1D) [Address 00C316]

Port P12 output mode (when timer 1 is used)

Port P13 output mode (when timer 2 is used)

Notes 1: Pay attention to the output level of T pin.
