software reset by "HW_CLKCTRL_RESET.CHIP" for i.MX28

[yuuki]

Dear All,

Our customer wants to use Softreset by HW_CLKCTRL_RESET.CHIP.
Watchdog reset is disabled by WDOG_POR_DIABLE=1 of HW_CLKCTRL_RESET register.

We refer to the following part.

MCIMX28RM.pdf (Rev2)
- Figure 11-3. Power-Up, Power-Down, and Reset Flow Chart(P.953)

According to Figure 11-3, the software reset by "HW_CLKCTRL_RESET.CHIP" is started from "Reset DCDC PIO Registers".

Which registers do "DCDC PIO Registers" mean concretely?
Does this include the reset about GPIO pin?

Best Regards,
Yuuki

"The HW_CLKCTRL_RESET_CHIP  software reset bit also initiates the full reset cycle and the power and the DCDC converter logic are also reset." This means that a full reset has been started making GPIO, and all modules to reset the only exception is the Ethernet which has a different logic. Please check Chapter 10.7 CHip Reset on the Reference Manual.

Have a great day,
Jaime
