IR0 (Interrupt request register 0)
The interrupt request register IR0 is an 8-bit
readable/writable register containing the setting for
enable/disable to accept interrupt sources.

Bit 6 : Timer 0 interrupt request bit
Bit 5 : Sets ‘0’.
Bit 4 : External interrupt request bit
Bit 3 : UART interrupt request bit
Bit 2 : Sets ‘0’.
Bit 1 : Sets ‘0’.
Bit 0 : LCD controller Interrupt Request bit

IR1 (Interrupt request register 1)
The interrupt request register IR1 is an 8-bit
readable/writable register containing the setting for
enable/disable to accept interrupt sources.
Bit 7
0
Bit 7 : Sets ‘0’.
Bit 6 : Timer 1 interrupt request bit
Bit 5 : Sets ‘0’.
Bit 4 : Clock interrupt request bit
Bit 3 : Sets ‘0’.
Bit 2 : PIO interrupt request bit
Bit 1 to 0 : Set ‘0’.

The interrupt request register IR0 and IR1 are also
used to wake up the chip from standby mode
(STOP mode, HALT mode) by setting the interrupt
to enable. If the interrupt enabled by the interrupt
request register IR0 and IR1 occurs, the chip will
wake up from standby mode. But also there are
interrupt sources which cannot use to wake up
from STOP mode. For more details, refer to
"Standby Function".
