REGISTER BIT DEFINITION
All the registers of the PSD are included here, for
reference. Detailed descriptions of these registers
can be found in the following sections.
Table 7. Data-In Registers - Ports A, B, C, D, E, F, and G
Note: Bit Definitions (Read only registers):
READ Port pin status when Port is in MCU I/O input mode.
Table 8. Data-Out Registers - Ports A, B, C, D, E, F, and G
Note: Bit Definitions:
Latched data for output to Port pin when pin is configured in MCU I/O output mode.
Table 9. Direction Registers - Ports A, B, C, D, E, F, and G
Note: Bit Definitions:
Portpin <i>
0 = Port pin <i> is configured in Input mode (default).
Portpin <i>
1 = Port pin <i> is configured in Output mode.
Table 10. Control Registers - Ports E, F, and G
Note: Bit Definitions:
Portpin <i>
0 = Port pin <i> is configured in MCU I/O mode (default).
Portpin <i>
1 = Port pin <i> is configured in Latched Address Out mode.
Table 11. Drive Registers - Ports A, B, D, E, and G
Note: Bit Definitions:
Portpin <i>
0 = Port pin <i> is configured for CMOS Output driver (default).
Portpin <i>
1 = Port pin <i> is configured for Open Drain output driver.
Table 12. Enable-Out Registers - Ports A, B, C, and F
Note: Bit Definitions (Read only registers):
Portpin <i>
0 = Port pin <i> is in tri-state driver (default).
Portpin <i>
1 = Port pin <i> is enabled.
