PWM/Timer 0 Counter Low Input Register

(PWM0_COUNT_IN_L)

Input Register 22 (016h) Read only

Reset Value: 0000 0000 (00h)

Bit 7-0: T0CI7-0 PWM/Timer 0 Counter MSB

In this register the current value of the Timer 0

Counter LSB can be read.

PWM/Timer 0 Status Register (PWM0_STATUS)

Input Register 23 (017h) Read only

Reset Value: 0000 0000 (00h)

Bit 7-4: Not Used

Bit 3: T0OVFL PWM/Timer 0 counter overflow flag

0: no overflow occurred since last reset

1: overflow occurred

Bit 2: T0OUT T0OUT pin value

0: T0OUT pin is at logical level 0

1: T0OUT pin is at logical level 1

Bit 1: T0RST Reset Status

0: PWM/Timer 0 is reset

1: PWM/Timer 0 is set

Bit 0: T0SST Start Status

0: PWM/Timer 0 is stopped

1: PWM/Timer 0 is running

PWM/Timer 0 Capture High Input Register

(PWM0_CAPTURE_H)

Input Register 24 (018h) Read only

Reset Value: 0000 0000 (00h)

Bit 7-0: T0CP15-8 PWM/Timer 0 Capture MSB

In this register the counter value after the last stop

can be read.

PWM/Timer 0 Capture Low Input Register

(PWM0_CAPTURE_L)

Input Register 25 (019h) Read only

Reset Value: 0000 0000 (00h)

Bit 7-0: T0CP7-0 PWM/Timer 0 Capture LSB

In this register the counter value after the last stop

can be read.

12.5.3 PWM/Timer 0 Output Registers.

PWM/Timer 0 Counter High Output Register

(PWM0_COUNT_OUT_H)

Output Register 7 (07h) Write only

Reset Value: 0000 0000 (00h)

Bit 7-0: T0CO15-8 PWM/Timer 0 Counter MSB

This register is used to write the Timer 0 Counter

value (MSB).

Note: this register is latched after writing the LSB

part (PWM_COUNT_OUT_L: see below). For this

reason this register must be written before the

LSB.

PWM/Timer 0 Counter Low Output Register

(PWM0_COUNT_OUT_L)

Output Register 8 (08h) Write only

Reset Value: 0000 0000 (00h)
