10.4.3 Interrupt culling function
452
• The interrupts to be culled are INTTQnCC0 (crest interrupt) and INTTQnOV (valley interrupt).
• The TQnOPT1.TQnICE bit is used to enable output of the INTTQnCC0 interrupt and the number of times the
• The TQnOPT1.TQnIOE bit is used to enable output of the INTTQnOV interrupt and the number of times the
• The TQnOPT1.TQnID4 to TQnOPT1.TQnID0 bits are used to specify the number of times for which an interrupt,
• The TQnOPT2.TQnRDE bit is used to specify whether transfer is to be culled or not.
• The TQnOPT0.TQnCMS bit is used to specify whether the registers with a transfer function are batch rewritten or

subject to counting of culling, is counted.
The interrupt is masked for the specified culling count and the masked interrupt occurs at the next occurrence
timing.
If it is specified that transfer is to be culled, transfer is executed at the same timing as the interrupt output after
culling. If it is specified that transfer is not to be culled, transfer is executed at the transfer timing after the
TQnCCR1 register has been written.
anytime rewritten.
The values of the registers are updated in synchronization with transferring when the TQnCMS bit is 0. When the
TQnCMS bit is 1, the values of the registers are immediately updated when a new value is written to the
registers.
Transfer is performed from the TQnCCRm register to the CCRm buffer register in synchronization with interrupt
culling timing.
Cautions 1. When using the interrupt culling function in the batch rewrite mode (transfer mode),
2. An interrupt is generated at the timing after culling.
execute the function in the intermittent batch rewrite mode (transfer culling mode).
