16.3.2
The bits 6 to 0 in HICR2 control interrupts from the LPC interface module to the slave processor
(this LSI). HICR3 and the bit 7 of HICR2 monitor the LPC interface pin states.
Bits 6 to 0 in HICR2 are initialized to H'00 by a reset or in hardware standby mode. The states of
the other bits are determined by the pin states.
The pin states can be monitored regardless of the LPC interface operating state or the operating
state of the functions that use pin multiplexing.
