All the registers in the PSD935G2 are included here for reference. Detail description of the
registers are found in the Functional Block section of the Data Sheet.
Bit definitions:
Read only registers, read Port pin status when Port is in MCU I/O input Mode.
Bit definitions:
Latched data for output to Port pin when pin is configured in MCU I/O output mode.
Bit definitions:
Set Register Bit to 0 = configure corresponding Port pin in Input mode (default).
Set Register Bit to 1 = configure corresponding Port pin in Output mode.
Bit definitions:
Set Register Bit to 0 = configure corresponding Port pin in MCU I/O mode (default).
Set Register Bit to 1 = configure corresponding Port pin in Latched Address Out mode.
Bit definitions:
Set Register Bit to 0 = configure corresponding Port pin in CMOS output driver (default).
Set Register Bit to 1 = configure corresponding Port pin in Open Drain output driver.
Bit definitions:
Set Register Bit to 0 = configure corresponding Port pin as CMOS output driver (default).
Set Register Bit to 1 = configure corresponding Port pin in Slew Rate mode.
Bit definitions: Read Only Register
