Section 3 Exception Handling
WKP5 to WKP0 Interrupts
Rev.5.00 Nov. 02, 2005 Page 58 of 500
REJ09B0027-0500
WKP5 to WKP0 interrupts are requested by input signals to pins WKP5 to WKP0. These six
interrupts have the same vector addresses, and are detected individually by either rising edge
sensing or falling edge sensing, depending on the settings of bits WPEG5 to WPEG0 in
IEGR2.
When pins WKP5 to WKP0 are designated for interrupt input in PMR5 and the designated
signal edge is input, the corresponding bit in IWPR is set to 1, requesting the CPU of an
interrupt. These interrupts can be masked by setting bit IENWP in IENR1.
