This is a multiplexed pin that has 3 functions (2 in
synchronous mode and 1 in asynchronous mode).
CFG66 - 66MHz Configuration (synchronous mode):
This pin is used to designate 66MHz operation. Tie
HIGH to enable 66MHz operation or tie LOW to
designate 33MHz operation.
SCAN_EN_H - Full-Scan Enable Control
(synchronous mode):
When SCAN_EN_H is LOW,
full-scan is in shift operation. When SCAN_EN_H is
HIGH, full-scan is in parallel operation.
Note: Valid only
in test mode. Pin is CFG66 in normal operation.
CLK_RATE – S_CLKOUT divider (asynchronous
mode):
Determines the S_CLKOUT frequency relation
to ASYNC_CLK_IN.
0: S_SCLKOUT is half the frequency of
ASYNC_CLK_IN.
1: S_CLKOUT is the same frequency as
ASYNC_CLK_IN.
Mode Selection:
Selector for Asynchronous or
Synchronous mode.

General Purpose I/O Data Pins:
The 4 general-
purpose signals are programmable as either input-only
or bi-directional signals by writing the GPIO output

Description
Test Clock.
Used to clock state information and data
into and out of the PI7C8150B during boundary scan.
Test Mode Select.
Used to control the state of the Test
Access Port controller.
Test Data Output.
When SCAN_EN_H is HIGH, it is
used (in conjunction with TCK) to shift data out of the
Test Access Port (TAP) in a serial bit stream.
Test Data Input.
When SCAN_EN_H is HIGH, it is
used (in conjunction with TCK) to shift data and
instructions into the Test Access Port (TAP) in a serial
bit stream.
Test Reset.
Active LOW signal to reset the Test Access
Port (TAP) controller into an initialized state.
