C.2 I/O Registers
The Advantech MIC-3329 EC communicates with main I/O. The LPC bus connects
the Intel
®
LPC signals. The Debug Port Unit is used to decode POST codes. The
watchdog is used to detect BIOS ready signals or recover BIOS code from redundant
BIOS flash. The hot-swap out-of-service LED control unit is used to control the blue
LED during hot-insert and hot-remove. The other signals in the miscellaneous unit
are for interfacing with corresponding I/O interface signals.
Other registers are accessed by ISA I/O, index port 0x272, data port 0x273.
