AT18F010/002/040/080 [Preliminary]
Table 6-1.
Open-collector bi-directional data pin. This pin has an internal 20 KΩ pull-up resistor.
Clock input. Used to increment the internal address and bit counter for reading and program-
ming. This pin has an internal 20 KΩ pull-up resistor.
Output Enable (active High) and RESET (active Low). A Low level on RESET/OE resets both
the address and bit counters. A High level (with CE Low) enables the data output driver. This pin
has an internal 20 KΩ pull-up resistor.
Chip Enable input (active Low). A Low level (with OE High) allows CLK to increment the address
counter and enables the data output driver. A High level on CE disables both the address and bit
counters and forces the device into a low-power standby mode. This pin has an internal 20 KΩ
pull-up resistor.
Configuration Pulse (open-drain output). Allows JTAG CONFIG instruction to initiate FPGA con-
figuration without powering down the FPGA. This is an open-drain output that is pulsed Low by
the JTAG CONFIG command.
