Description

EXT_PWR_DWN

External Power-Down. Digital input (active high). A high level on this pin initiates the

currently programmed power-down mode.

SYNC_CLK

Clock Output. Digital output. Many of the digital inputs on the chip, such as I/O_UPDATE,

PS[2:0], and the parallel data port (D0 to D31), must be set up on the rising edge of

this signal.

MASTER_RESET

Master Reset. Digital input (active high). Clears all memory elements and sets registers to

default values.

I/O_UPDATE

Input/Output Update. Digital input (active high). A high on this pin transfers the contents of

the input/output buffers to the corresponding internal registers.

EPAD

Exposed Pad. The EPAD must be soldered to ground.

1 I = input, O = output.
