Initial value
Slave Read/Write
Host Read/Write
HICR2 and HICR3 contain flags and bits that control interrupts from the host interface (LPC)
module to the slave processor, and bits that monitor host interface pin states.
Bits 6 to 0 of HICR2 are initialized to H'00 by a reset and in hardware standby mode. The states of
the other bits are determined by the pin states.
HICR2 Bit 7—GA20 Pin Monitor (GA20)
HICR3 Bit 7—LFRAME
HICR3 Bit 6—CLKRUN
HICR3 Bit 5—SERIRQ Pin Monitor (SERIRQ)
HICR3 Bit 4—LRESET
HICR3 Bit 3—LPCPD
HICR3 Bit 2—PME
HICR3 Bit 1—LSMI
HICR3 Bit 0—LSCI Pin Monitor (LSCI)
These are pin state monitoring bits. The pin states can be monitored regardless of the host
interface operating state or the operating state of the functions that use pin multiplexing.
