General-Purpose Input/Output 35
JTAG test data input (TDI) with internal pullup. TDI is clocked into the selected register
(instruction or data) on a rising edge of TCK
General-Purpose Input/Output 36
JTAG test-mode select (TMS) with internal pullup. This serial control input is clocked
into the TAP controller on the rising edge of TCK.
General-Purpose Input/Output 37
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)
General-Purpose Input/Output 38
JTAG test clock with internal pullup
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.
