Interrupt priority level select bits (Note 1)
Interrupt request bit
0 : No interrupt requested
1 : Interrupt requested
Interrupt control register bit configuration for A-D converter, UART0, UART1, UART2,
timer A0 to timer A9, and timer B0 to timer B2.
76543210
Interrupt priority level select bits (Note 1)
Interrupt request bit (Note 2)
0 : No interrupt requested
1 : Interrupt requested
Polarity select bit
0 : Interrupt request bit is set to “1” at “H” level when level sense is selected;
this bit is set to “1” at falling edge when edge sense is selected.
1 : Interrupt request bit is set to “1” at “L” level when level sense is selected;
this bit is set to “1” at rising edge when edge sense is selected.
Level/Edge select bit
0 : Edge sense
1 : Level sense
Interrupt control register bit configuration for INT0– INT7
Notes 1: Use the MOVM (MOVMB) instruction or the STA (STAB, STAD) instruction for writing to this bit.
2: Interrupt request bits of INT0 to INT7 are invalid when the level sense is selected.
