    I am referring the TRM of DM3730 and modifying the pad configurations on an EVM 3530 accordingly. I couldn't understand the following properly.

    1) What are CORE power domain and WKUP power domain?
    2) What is core control module and Wake-Up control module?
    3) In EVM 3530 source code, in pad configurations, certain pins are defined as PAD_ENTRY and certain others as WKUP_PAD_ENTRY. What makes the difference?

    #define PAD_ENTRY(x,y) {PAD_ID(x),y,0},
    #define WKUP_PAD_ENTRY(x,y) {WKUP_PAD_ID(x),y,0},

    #define I2C3_PADS \
    PAD_ENTRY(I2C3_SCL, INPUT_ENABLED | PULL_RESISTOR_DISABLED | MUXMODE(0)) \
    PAD_ENTRY(I2C3_SDA, INPUT_ENABLED | PULL_RESISTOR_DISABLED | MUXMODE(0))

    #define I2C4_PADS \
    WKUP_PAD_ENTRY(I2C4_SCL, INPUT_ENABLED | PULL_RESISTOR_DISABLED | MUXMODE(0)) \
    WKUP_PAD_ENTRY(I2C4_SDA, INPUT_ENABLED | PULL_RESISTOR_DISABLED | MUXMODE(0))

    Thanks in advance.
