Description

Pulse Width Timer Register 1

Fields

PWTOV

PWT Counter Overflow

0 (0): PWT counter no overflow.

1 (1): PWT counter runs from 0xFFFF to 0x0000.

PWTRDY

PWT Pulse Width Valid

0 (0): PWT pulse width register(s) is not up-to-date.

1 (1): PWT pulse width register(s) has been updated.

PWTSR

PWT Soft Reset

0 (0): No action taken.

1 (1): Writing 1 to this field will perform soft reset to PWT.

POVIE

PWT Counter Overflow Interrupt Enable

0 (0): Disable PWT to generate interrupt when PWTOV is set.

1 (1): Enable PWT to generate interrupt when PWTOV is set.

PRDYIE

PWT Pulse Width Data Ready Interrupt Enable

0 (0): Disable PWT to generate interrupt when PWTRDY is set.

1 (1): Enable PWT to generate interrupt when PWTRDY is set.

PWTIE

PWT Module Interrupt Enable

0 (0): Disables the PWT to generate interrupt.

1 (1): Enables the PWT to generate interrupt.

PWTEN

PWT Module Enable

0 (0): The PWT is disabled.

1 (1): The PWT is enabled.

PRE

PWT Clock Prescaler (CLKPRE) Setting

0 (000): Clock divided by 1.

1 (001): Clock divided by 2.

2 (010): Clock divided by 4.

3 (011): Clock divided by 8.

4 (100): Clock divided by 16.

5 (101): Clock divided by 32.

6 (110): Clock divided by 64.

7 (111): Clock divided by 128.

EDGE

PWT Input Edge Sensitivity

0 (00): The first falling-edge starts the pulse width measurement, and on all the subsequent falling edges, the pulse width is captured.

1 (01): The first rising edge starts the pulse width measurement, and on all the subsequent rising and falling edges, the pulse width is captured.

2 (10): The first falling edge starts the pulse width measurement, and on all the subsequent rising and falling edges, the pulse width is captured.

3 (11): The first-rising edge starts the pulse width measurement, and on all the subsequent rising edges, the pulse width is captured.

PINSEL

PWT Pulse Inputs Selection

0 (00): PWTIN[0] is enabled.

1 (01): PWTIN[1] is enabled.

2 (10): PWTIN[2] enabled.

3 (11): PWTIN[3] enabled.

PCLKS

PWT Clock Source Selection

0 (0): Bus clock is selected as the clock source of PWT counter.

1 (1): Alternative clock is selected as the clock source of PWT counter.

PPW

Positive Pulse Width
