12.5.2 PWM/Timer 0 Input Registers.
PWM/Timer 0 Counter High Input Register
(PWM0_COUNT_IN_H)
Input Register 21 (015h) Read only
Reset Value: 0000 0000 (00h)
Bit 7-0: T0CI15-8 PWM/Timer 0 Counter MSB
In this register the current value of the Timer 0
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.
