22 / 124 page  PSD register description and address offsets PSD4235G2V 22/124 4 PSD register description and address offsets Table 5 shows the offset addresses to the PSD registers relative to the CSIOP base address. The CSIOP space is the 256 bytes of address that is allocated by the user to the internal PSD registers. Table 5 provides brief descriptions of the registers in CSIOP space. The following sections give a more detailed description. Table 5. Register address offset Register name Port A Port B Port C Port D Port E Port F Port G Other(1) Description Data In 00 01 10 11 30 40 41 Reads Port pin as input, MCU I/O input mode Control 32 42 43 Selects mode between MCU I/O or Address Out Data Out 04 05 14 15 34 44 45 Stores data for output to Port pins, MCU I/O output mode Direction 06 07 16 17 36 46 47 Configures Port pin as input or output Drive Select 08 09 18 19 38 48 49 Configures Port pins as either CMOS or Open Drain on some pins, while selecting high slew rate on other pins.
