PC87338 Datasheet, PDF (217/221 Pages) National Semiconductor (TI) – ACPI 1.0 and PC98/99 Compliant SuperI/O

Glossary
11-bit address mode
In this mode, the Chip decodes address lines
A0-A10, A11-A15 are masked to 1, and
UART2 is a fully featured 16550 UART. The
mode is configured during reset, via the CFG0
strap pin.
16-bit address mode
In this mode, the Chip decodes address lines
A0-A15 and SCC2 is a 16550 UART with
SIN2/SOUT2 interface signals only. The mode
is configured during reset, via the CFG0 strap
pin.
AFIFO
Address FIFO for the parallel port in Extended
Capabilities Port mode.
ASC
The register that configures the Advanced Su-
per I/O chip, i.e., the PC87338/VLJ or the
PC87338VJG.
ASK-IR
Amplitude Shift Keying Infrared.
BGD(H) and BGD(L)
Baud Generator Divisor Ports (High and Low
bytes) for the SCCs.
BSR
Bank Selection Register for the SCCs.
CCR
Configuration Control Register of the Floppy
Disk Controller (FDC).
CFIFO
Parallel port data FIFO in Extended Capabili-
ties Port (ECP) mode.
CNFGA and CNFGB
Configuration registers A and B for the parallel
port in Extended Capabilities Port mode.
CEIR Mode
This IR mode supports all four protocols cur-
rently used in remote-controlled home enter-
tainment equipment. Also called TV-Remote
mode.

Digital Output Register of the Floppy Disk
Controller (FDC).
DSR
Data rate Select Register of the Floppy Disk
Controller (FDC) and the data Status Register
in Extended Capabilities Port mode.
DTR
Data Register of the parallel port.
EAR
Extended Auxiliary Register of the parallel
port in Extended Capabilities Port (ECP)
modes.
ECP
Extended Capabilities Port.
ECR
Extended Control Register for the parallel port
in Extended Capabilities Port mode.
EDR
Extended Data Register for the parallel port in
extended Capabilities Port (ECP) modes.
EIR
Two expressions:
Extended Index Register of the parallel port
Extended Capabilities Port (ECP) modes.
Event Identification Register for SCC1 and
SCC2 for read cycles.
EPP
Enhanced Parallel Port.
