Description
NMI Block Mode
Selects whether an NMI interrupt is held until the BL bit
in SR is cleared to 0 or detected immediately when the
BL bit in SR of the CPU is set to 1.
0: An NMI interrupt is held when the BL bit in SR is set
1: An NMI interrupt is not held when the BL bit in SR is
Note: If interrupts are accepted with the BL bit in SR
NMI Edge Select
Selects whether an interrupt request signal to the NMI
pin is detected at the rising edge or the falling edge.
0: An interrupt request is detected at the falling edge of
1: An interrupt request is detected at the rising edge of
IRL Pin Mode 0
Selects whether IRQ/IRL3 to IRQ/IRL0 are used as
encoded interrupt requests (IRL3 to IRL0) or as four
independent interrupts (IRQ3 to IRQ0 interrupts).
0: IRQ/IRL3 to IRQ/IRL0 are used as the encoded
1: IRQ/IRL3 to IRQ/IRL0 are used as four independent
IRL Pin Mode 1
Selects whether IRQ/IRL7 to IRQ/IRL4 are used as 4-
bit level-encoded interrupt requests (IRL7 to IRL4
interrupts) or as four independent interrupts (IRQ7 to
IRQ4 interrupts).
0: IRQ/IRL7 to IRQ/IRL4 are used as the 4-bit level-
1: IRQ/IRL7 to IRQ/IRL4 are used as four independent
