10.4.4 Setting alarm of real-time counter
R01UH0028EJ0400 Rev.4.00
Sep 27, 2010
Set time of alarm after setting 0 to WALE first.
Remarks 1. ALARMWM, ALARMWH, and ALARMWW may be written in any sequence.
2. Fixed-cycle interrupts and alarm match interrupts use the same interrupt source (INTRTC). When using
these two types of interrupts at the same time, which interrupt occurred can be judged by checking the
fixed-cycle interrupt status flag (RIFG) and the alarm detection status flag (WAFG) upon INTRTC
occurrence.
