PIN NO.
PIN NAME I/O/Z DESCRIPTION
PZ PN
PZP PFP
GPIO35 71 57 I/O/Z General-purpose input/output 35
TDI I JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register
(instruction or data) on a rising edge of TCK.
GPIO36 72 58 I/O/Z General-purpose input/output 36
TMS I JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked
into the TAP controller on the rising edge of TCK.
GPIO37 70 56 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 67 54 I/O/Z General-purpose input/output 38
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.
TCK I JTAG test clock with internal pullup
