Programmable Pin-keeper Option for Inputs and I/Os
The ATF1504ASV(L) offers the option of programming all input and I/O pins so that pin keeper circuits can be utilized.
When any pin is driven high or low and then subsequently left floating, it will stay at that previous high- or low-level. This cir-
cuitry prevents unused input and I/O lines from floating to intermediate voltage levels, which causes unnecessary power
consumption and system noise. The keeper circuits eliminate the need for external pull-up resistors and eliminate their DC
power consumption.
