The control signals for the configuration EEPROM (CE, RESET/OE and CCLK) interface directly
with the FPGA device control signals. All FPGA devices can control the entire configuration pro-
cess and retrieve data from the configuration EEPROM without requiring an external intelligent
controller.
The configuration EEPROM RESET/OE and CE pins control the tri-state buffer on the DATA
output pin and enable the address counter. When RESET/OE is driven High, the configuration
EEPROM resets its address counter and tri-states its DATA pin. The CE pin also controls the
output of the AT17LV series configurator. If CE is held High after the RESET/OE reset pulse, the
counter is disabled and the DATA output pin is tri-stated. When OE is subsequently driven Low,
the counter and the DATA output pin are enabled. When RESET/OE is driven High again, the
address counter is reset and the DATA output pin is tri-stated, regardless of the state of CE.
When the configurator has driven out all of its data and CEO is driven Low, the device tri-states
the DATA pin to avoid contention with other configurators. Upon power-up, the address counter
is automatically reset.
This is the default setting for the device. Since almost all FPGAs use RESET Low and OE High,
this document will describe RESET/OE.
