ST52510xx ST52513xx
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 LSB
In this register the current value of the Timer 0
Counter LSB can be read.
Warning: Both of the PWMx_COUNT_IN_x
registers must be always read. To avoid side
effects, the values stored inside these registers are
frozen, and new updates cannot be stored, until
both the values are 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
Bit 2: T0OUT T0OUT pin value
Bit 1: T0RST Reset Status
Bit 0: T0SST Start Status
78/136

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.
