Counter register high (CNTRH)
Reset value: 0000 0000 (00h)
Counter register low (CNTRL)
This 12-bit register is read by software and cleared by hardware after a reset. The counter is
incremented continuously as soon as a counter clock is selected. To obtain the 12-bit value, software
should read the counter value in two consecutive read operations. As there is no latch, it is
recommended to read LSB first. In this case, CNTRH can be incremented between the two read
operations and to have an accurate result when f
CNTRL values close to FFh are read.
When a counter overflow occurs, the counter restarts from the value specified in the ATR register.
Reset value: 0000 0000 (00h)
