IA186XL/IA188XL
16-Bit Microcontrollers
2.2
Descriptions of the pin and signal functions for the IA186XL microcontroller are provided in
Table 7.
Several of the IA186XL 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 7, 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 the PLCC, PQFP, and LQFP 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. Signals not used in a specific package type are designated “NA.”

Latched address bit a1
Latched address bit a2
address bits 16–19. Input/Output. These pins
provide the four most-significant bits of the
Address Bus.
address/data bits 0–15. Input/Output. These
pins provide the multiplexed Address Bus and
Data Bus. During the address portion of the
IA186XL bus cycle, Address Bits [0–15] are
presented on the bus and can be latched
using the ale signal (see next table entry).
During the data portion of the IA186XL bus
cycle, 8- or 16-bit data are present on these
lines.
