Descriptions of the pin and signal functions for the IA82527 Serial Communications Controller
are provided in Table 3.
Several of the IA82527 pins have different functions depending on the operating mode of the
device. Each of the different
signals
supported by a pin is listed and defined in Table 3, indexed
alphabetically in the first column of the table. Additionally, the name of the pin associated with
the signal as well as the pin numbers for both the PLCC and QFP packages are provided in the
“Pin” column. If the signal and pin names are the same, no entry is provided in the “Pin-Name”
column.

When the IA82527 is configured to operate in the 8-bit non-
multiplexed non-Intel
architecture mode (Mode 3), these lines
provide the 8-bit address bus input to the device.

. Input/Output. Mode 1.
When the IA82527 is configured to operate in the 16-bit multiplexed
Intel
architecture mode (Mode 1), these lines provide the 16-bit
address bus (input) and the 16-bit data bus (input/output) for the
device.

When the IA82527 is configured to operate in either the 8-bit
multiplexed Intel
architecture mode (Mode 0) or the 16-bit
multiplexed Intel
architecture mode (Mode 1), this signal latches the
address into the device during the address phase of the bus cycle.
