15.4.1 Register Description
The EPORT programming model consists of these registers:
15.4.1.1 EPORT Pin Assignment Register (EPPAR)
Freescale Semiconductor
• The EPORT pin assignment register (EPPAR) controls the function of each pin
• The EPORT data direction register (EPDDR) controls the direction of each one of the pins
• The EPORT interrupt enable register (EPIER) enables interrupt requests for each pin
• The EPORT data register (EPDR) holds the data to be driven to the pins.
• The EPORT pin data register (EPPDR) reflects the current state of the pins.
• The EPORT flag register (EPFR) individually latches EPORT edge events.

S = CPU supervisor mode access only. S/U = CPU supervisor or user mode access. User mode accesses to
supervisor only addresses have no effect and result in a cycle termination transfer error.
Writing to reserved address locations has no effect, and reading returns 0s.
