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)
