19.3.4 Interrupt control register (xxICn)
each maskable interrupt request.

Sep 30, 2010
The xxICn register is assigned to each interrupt request signal (maskable interrupt) and sets the control conditions for
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 47H.
Caution Disable interrupts (DI) or mask the interrupt to read the xxICn.xxIFn bit. If the xxIFn bit is read while
The addresses and bits of the interrupt control registers are as follows.
Note The flag xxlFn is reset automatically by the hardware if an interrupt request signal is acknowledged.
Remark
interrupts are enabled (EI) or while the interrupt is unmasked, the correct value may not be read
when acknowledging an interrupt and reading the bit conflict.
xx: Identification name of each peripheral unit (see Table 19-2 Interrupt Control Register (xxICn))
n: Peripheral unit number (see Table 19-2 Interrupt Control Register (xxICn)).
