ST52510xx ST52513xx
PWM/Timer 1 Control Register 2 (PWM1_CR2)
Configuration Register 13 (0Dh) Read/Write
Reset Value: 0000 0000 (00h)
Bit 7-6: Not Used
Bit 5: T1WAV T1OUT Waveform
Bit 4-0: T1PRESC PWM/Timer 1 Prescaler
12.6.2 PWM/Timer 1 Input Registers.
PWM/Timer 1 Counter High Input Register
(PWM1_COUNT_IN_H)
Input Register 26 (01Ah) Read only
Reset Value: 0000 0000 (00h)
Bit 7-0: T1CI15-8 PWM/Timer 1 Counter MSB
In this register the current value of the Timer 1
Counter MSB 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 1 Counter Low Input Register
(PWM1_COUNT_IN_L)
Input Register 27 (01Bh) Read only
Reset Value: 0000 0000 (00h)

Bit 7-0: T1CI7-0 PWM/Timer 1 Counter LSB
In this register the current value of the Timer 1
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 1 Status Register (PWM1_STATUS)
Input Register 28 (01Ch) Read only
Reset Value: 0000 0000 (00h)
Bit 7-4: Not Used
Bit 3: T1OVFL PWM/Timer 1 counter overflow flag
Bit 2: T1OUT T1OUT pin value
Bit 1: T1RST Reset Status
Bit 0: T1SST Start Status
PWM/Timer 1 Capture High Input Register
(PWM1_CAPTURE_H)
Input Register 29 (01Dh) Read only
Reset Value: 0000 0000 (00h)
Bit 7-0: T1CP15-8 PWM/Timer 1 Capture MSB
In this register the counter value after the last stop
can be read.
