Bit 0 = CMPIE Compare Interrupt Enable bit
Counter register 1 High (CNTR1H)
Reset value: 0000 0000 (00h)
Counter register 1 Low (CNTR1L)
Reset value: 0000 0000 (00h)
Bits 15:12 = Reserved
Bits 11:0 = CNTR1[11:0] Counter value
CNTR1_7
This bit is read/write by software and cleared by hardware after a reset. it can be used
to mask the interrupt generated when any of the cmpfx bit is set.
0: Output Compare Interrupt Disabled.
1: Output Compare Interrupt Enabled.
This 12-bit register is read by software and cleared by hardware after a reset. The
counter CNTR1 increments 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,
CNTR1H can be incremented between the two read operations and to have an
accurate result when f
close to FFh are read.
When a counter overflow occurs, the counter restarts from the value specified in the
ATR1 register.
