I/O/Z DESCRIPTION
PN PAG RSH
NAME
PIN # PIN # PIN #
GPIO37 58 46 41 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 57 45 40 I/O/Z General-Purpose Input/Output 38
TCK I JTAG test clock with internal pullup
XCLKIN I 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.
