Pin Description
Input
–
Dedicated in-system programming enable input pin. This pin
is brought low to enable the programming mode. The MODE, SDI,
SDO and SCLK options become active.
Input
–
This pin performs two functions. It is a dedicated input pin when
ispEN is logic high. When ispEN is logic low, it functions as an input
pin to load programming data into the device. SDI/IN 0 also is used as
one of the two control pins for the isp state machine.
Input
–
This pin performs two functions. It is a dedicated input pin when
ispEN is logic high. When ispEN is logic low, it functions as a pin to
control the operation of the isp state machine.
Input/Output
–
This pin performs two functions. It is a dedicated input
pin when ispEN is logic high. When ispEN is logic low, it functions as
an output pin to read serial shift register data.
Input
–
This pin performs two functions. It is a dedicated input when
ispEN is logic high. When ispEN is logic low, it functions as a clock pin
for the Serial Shift Register.
