Gio Module - Texas Instruments UCD3138 Technical Reference Manual

The GIO Module offers general purpose input/output pins. These pins can also be used as inputs to the
fault logic above. These pins can also be used for fault interrupts. The GIO registers also control and
monitor the external interrupt pin. They are similar to GPIO functions on many microcontrollers.
GIO Registers have the following attributes:
• Addresses placed on word boundaries
• Byte, Half-word and Word Writes are permitted
• All Registers can be read in any mode
• All Registers are writeable
