2.8 Supply, Factory Test, and Reset Signal Descriptions
Signal Name:
Signal Description:
Signal Type:
This active-low asynchronous signal causes the device to be reset. When this signal is forced low, it
causes all of the internal registers to be forced to their default states. The device is held in a reset state as
long as this signal is low. This signal should be activated after the clocks MCLK and FTCLK are valid,
and must be returned high before the device can be configured for operation.
