19.3.2
Bits 6 to 0 in HICR2 control interrupts from the host interface (LPC) module to the slave
processor (this LSI). Bit 7 in HICR2 and HICR3 monitor host interface pin states.
The pin states can be monitored regardless of the host interface operating state or the operating
state of the functions that use pin multiplexing.

LSCI output Bit
Controls LSCI output in combination with the LSCIE
bit. For details, refer to description on the LSCIE bit
in HICR0.
GA20 Pin Monitor
LPC Reset Interrupt Flag
This bit is a flag that generates an ERRI interrupt
when an LPC hardware reset occurs.
0: [Clearing conditions]
1: [Setting condition]
LPC Shutdown Interrupt Flag
This bit is a flag that generates an ERRI interrupt
when an LPC hardware shutdown request is
generated.
0: [Clearing conditions]
1: [Setting condition]
