DESCRIPTION

NAME

PIN NO.

PAG

PIN NO.

RSH

PIN NO.

GPIO37

I/O/Z

General-Purpose Input/Output 37

TDO

O/Z

JTAG scan out, test data output (TDO). The contents of the selected register

(instruction or data) are shifted out of TDO on the falling edge of TCK (8 mA

drive)

GPIO38

I/O/Z

General-Purpose Input/Output 38

TCK

JTAG test clock with internal pullup

XCLKIN

External Oscillator Input. The path from this pin to the clock block is not gated by

the mux function of this pin. Care must be taken to not enable this path for

clocking if it is being used for the other functions.
