• This bit enables or disables IF flag interrupts.
Setting this bit to "0" : disables IF flag interrupts.
Setting this bit to "1" : an IF flag interrupt request is outputted when both the IE bit (T00CR1/
T01CR1:IE) and the IF flag (T00CR1/T01CR1:IF) are set to "1".
These bits select the count clock.
• The count clock is generated by the prescaler. Refer to 6.12 Operating Explanation of Prescaler.
• Write access to these bits is nullified during timer operation (T00CR1/T01CR1:STA = "1").
• The clock selection of T01CR0 (timer 01) is nullified during 16-bit operation.
• These bits cannot be set to "111
write "111 " with the PWC or input capture function in use resets the bits to "000
B
also reset to "000 " if the timer enters the input capture operation mode with the bits set to "111
