Priority
Default
The default priority determines the sequence of processing vectored interrupts if two or more maskable
interrupts occur simultaneously. Zero indicates the highest priority and 27 indicates the lowest priority.
Basic configuration types (A) to (D) correspond to (A) to (D) in Figure 19-1.
When bit 1 (LVIMD) of the low-voltage detection register (LVIM) is cleared to 0.
When 8-bit timer/event counter 51 is used in the carrier generator mode, an interrupt is generated upon
the timing when the INTTM5H1 signal is generated (see Figure 9-13 Transfer Timing).
