DESCRIPTION

This active high input indicates that the

power (VCC) is valid. For device

operation, PWRGD must be active.

When PWRGD is inactive, all inputs to

the device are disconnected and put into

a low power mode; all outputs are put

into high impedance. The contents of all

registers are preserved as long as VCC

has a valid value. The driver current

drain in this mode drops to ISTBY -

standby current. This input has an

internal 30 ua pull-up.

O4

This is the Game Port Chip Select output

- active low. It will go active when the I/O

address, qualified by AEN, matches that

selected in Configuration register CR1E.
