IA186EB/IA188EB
8-Bit/16-Bit Microcontrollers
2.2
Descriptions of the pin and signal functions for the IA186EB microcontroller are provided in
Table 7.
Several of the IA186EB 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, LQFP, and PQFP packages
are provided in the ―Pin‖ column. Signals not used in a specific package type are designated
―NA.‖

address Bits [16–19]. Input/Output. These pins
provide the four most-significant bits of the
Address Bus. During the address portion of the
IA186EB bus cycle, Address Bits [16–19] are
presented on the bus and can be latched using
the ale signal (see table entry). During the data
portion of the IA186EB bus cycle, these lines
are driven to a logic 0.
address/data Bits [0–15]. Input/Output. These
pins provide the multiplexed Address Bus and
Data Bus. During the address portion of the
IA186EB 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 IA186EB bus cycle, 8- or
16-bit data are present on these lines.
