Terminal Functions
TERMINAL NAME
DESCRIPTION
A1–A20
Normal-function A-bus I/O ports. See function table for normal-mode logic.
B1–B20
Normal-function B-bus I/O ports. See function table for normal-mode logic.
CLKAB, CLKBA
Normal-function clock inputs. See function table for normal-mode logic.
CLKENAB, CLKENBA
Normal-function clock enables. See function table for normal-mode logic.
GND
Ground
LEAB, LEBA
Normal-function latch enables. See function table for normal-mode logic.
OEAB, OEBA
Normal-function output enables. See function table for normal-mode logic. An internal pullup at each terminal
forces the terminal to a high level if left unconnected.
TCK
Test clock. One of four terminals required by IEEE Standard 1149.1-1990. Test operations of the device are
synchronous to TCK. Data is captured on the rising edge of TCK and outputs change on the falling edge of TCK.
TDI
Test data input. One of four terminals required by IEEE Standard 1149.1-1990. TDI is the serial input for shifting
data through the instruction register or selected data register. An internal pullup forces TDI to a high level if left
unconnected.
TDO
Test data output. One of four terminals required by IEEE Standard 1149.1-1990. TDO is the serial output for shifting
data through the instruction register or selected data register.
TMS
Test mode select. One of four terminals required by IEEE Standard 1149.1-1990. TMS directs the device through
its TAP controller states. An internal pullup forces TMS to a high level if left unconnected.
VCC
Supply voltage
