IA186XL/IA188XL
16-Bit Microcontrollers
2.3
Descriptions of the pin and signal functions for the IA188XL microcontroller are provided in
Table 8.
Several of the IA188XL 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 8, 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, QFP, 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.

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 015. Input/Output.
These pins provide the multiplexed Address
Bus and Data Bus. During the address
portion of the IA186XL bus cycle, address bits
0 through 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.
valid address information is provided for the
entire bus cycle
