Specifications and Timing Diagrams
Powering Up
TAG memory is available when the boot-up either from the internal embedded Flash or from the external SPI Flash
boot PROM is complete. If the embedded Flash is blank, the boot up will not work. It is recommended to wait for the
same amount of delay as if the embedded configuration has been programmed before accessing the TAG memory.
If the boot-up is from external SPI Flash, longer delay time should be given or check the DONE pin for a high first
before accessing the TAG memory.
The SPI interface needs the low-to-high transition on the Chip Select pin to reset. During power-up, the low-to-high
transition is assured by requiring the CLK pin tracking the VCC. The other method is to drive the Chip Select pin to
high then low then high to reset the SPI interface before shifting the first command into the device.
