Input — Dedicated in-system programming enable input pin.
This pin is brought low to enable the programming mode. The
TMS, TDI, TDO and TCK controls become active.
Input — This pin performs two functions. When ispEN is logic
low, it functions as an input pin to load programming data into the
device. TDI/IN 0 also is used as one of the two control pins for the
ISP state machine. When ispEN is high, it functions as a
dedicated input pin.

Input — This pin performs two functions. When ispEN is logic low,
it functions as a pin to control the operation of the ISP state
machine. When ispEN is high, it functions as a dedicated input
pin.
TMS/IN 1
Output/Input — This pin performs two functions. When ispEN is
logic low, it functions as an output pin to read serial shift register
data. When ispEN is high, it functions as a dedicated input pin.
