Chapter 4 was updated to reflect the correct number of GPIOs.
2. In the boot code, determine the type of reset. If the reset was a GPIO reset, then refresh all the
Mechanical and Thermal Specifications). For example, the GPIO reset time is ~360
microseconds, leaving an SDRAM refresh time of (64 ms - .360 ms) = 63.64 ms. Use this time
to program the MDREFR[DRI].
SDRAM rows. Refreshing all the SDRAM rows preserves their value in case GPIO reset
occurs again.
