Chapter 37 Output Compare
4.Registers
• bit7: Interrupt request flag (output compare 1)
ICP1
0 Interrupt request not present
1 Interrupt request present
• If free-run timer count value TCDT0 matches the output compare register OCCP1, ICP1 becomes "1".
• Interrupt request is enabled when the interrupt permission bit (ICP1) is set to "1".
• If the interrupt request flag becoming "1" and writing of "0" to it happen at the same time, the interrupt
request flag will become "1" (flag setting is given priority).
• When using an external clock as the free-run timer operation clock, at least one external clock input is
necessary after compare match for output compare-match output and interrupt generation.
• bit6: Interrupt request flag (output compare 0)
ICP0
0 Interrupt request not present
1 Interrupt request present
• If free-run timer count value TCDT0 matches output compare register OCCP0, ICP0 becomes "1".
• Interrupt request is enabled when the interrupt permission bit (ICP0) is "1".
• If the interrupt request flag becoming "1" and writing of "0" to it happen at the same time, the interrupt
request flag will become "1" (flag setting is given priority).
• When using an external clock as the free-run timer operation clock, at least one external clock input is
necessary after compare match for output compare-match output and interrupt generation.
• bit5: Interrupt request enable (output compare 1)
ICE1
0 Disable output compare 1 interrupt requests
1 Enable output compare 1 interrupt requests
• bit4: Interrupt request enable (output compare 0)
ICE0
0 Disable output compare 0 interrupt requests
1 Enable output compare 0 interrupt requests
• bit3-bit2: Undefined
• bit1: Enable operation requests (output compare 1)
CST1
0 Stop operation of output compare 1
1 Enable operation of output compare 1
• A bit that enables a comparison operation between the free-run timer count value and the output
compare register (TCDT0 and OCCP1).
• Before enabling the operation, always set a value to compare register OCCP1.
• If you stop the free-run timer, output compare also stops.
