This LSI has an on-chip LPC interface.
The LPC performs serial transfer of cycle type, address, and data, synchronized with the 33 MHz
PCI clock. It uses four signal lines for address/data, and one for host interrupt requests. This LPC
module supports only I/O read cycle and I/O write cycle transfers.
It is also provided with power-down functions that can control the PCI clock and shut down the
host interface.
19.1
IFHSTL0A_000020020700
Supports LPC interface I/O read cycles and I/O write cycles
Has three register sets comprising data and status registers
Supports SERIRQ
Eleven interrupt sources
Uses four signal lines (LAD3 to LAD0) to transfer the cycle type, address, and data.
Uses three control signals: clock (LCLK), reset (LRESET), and frame (LFRAME).
The basic register set comprises three bytes: an input register (IDR), output register (ODR),
and status register (STR).
Channels 1 and 2 have fixed I/O addresses of H'60/H'64 and H'62/H'66, respectively. A fast
A20 gate function is also provided.
The I/O address can be set for channel 3. Sixteen bidirectional data register bytes can be
manipulated in addition to the basic register set.
Host interrupt requests are transferred serially on a single signal line (SERIRQ).
On channel 1, HIRQ1 and HIRQ12 can be generated.
On channels 2 and 3, SMI, HIRQ6, and HIRQ9 to HIRQ11 can be generated.
Operation can be switched between quiet mode and continuous mode.
The CLKRUN signal can be manipulated to restart the PCI clock (LCLK).
The LPC module can be shut down by inputting the LPCPD signal.
Three pins, PME, LSMI, and LSCI, are provided for general input/output.
