                            Power Mode
EPCQ-L devices support active and standby power modes. When the nCS signal is low, the device is enabled and is in active power mode. The FPGA is configured while the EPCQ-L device is in active power mode. When the nCS signal is high, the device is disabled but remains in active power mode until all internal cycles are completed, such as write or erase operations. The EPCQ-L device then goes into standby power mode. The ICC1 and ICC0 parameters list the VCC supply current when the device is in active and standby power modes. Refer to Table 5.
