Table 10-19. Timing Specifications
Figure 10-49. Generic Timing Diagram
Programming via the SPI Interface
Since the SSPIA module is an internal module, I/Os can be treated as I/Os of any other soft module. Therefore,
they can be routed to other internal modules, or they can go out to I/O pads. The recommended routing is to the
sysCONFIG port pins.

Note: If the READ_TAG command is issued without first loading the WRITE_EN command, the device will need extra time,
up to 20µs maximum, to transfer the data from TAG Flash to the data-shift register.
