Section 6 Interrupt Controller (INTC)
6.3 Register Descriptions
The INTC has the following registers. These registers are used to set the interrupt priorities and
control detection of the external interrupt input signal.

Notes: Two access cycles are needed for word access, and four access cycles for longword
access.
1. When the NMI pin is high, becomes H'8000; when low, becomes H'0000.
2. Only 0 can be written after reading 1, to clear the flag.
