IO retention is supported on MCU_GENERAL and
CANUART IOs, MCU Scratch Memory, SerDes PHY, and DDR PHY.
- The control of the retention of LVCMOS IOs is
performed via the corresponding PADCONFIG register listed in Control Module
(CTRL_MMR). For more information about the exact PADCONFIG register see
Pin Multiplexing Table in the device-specific Datasheet.
- MCU-Scratch-Memory - TBD
- The control of the retention of SERDES PHY is
performed via CTRLMMR_SERDESx_CTRL[8] RET_EN, x = 0 to 4. For more information
about control registers, see Control Module (CTRL_MMR).
- The control of DDRSS retention is controlled via external DDR_RET pin.
