10 / 16 page Specifications ispLSI 1032 10 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.
