18.9
The port output enable (POE) can be used to establish a high-impedance state for high-current
pins, by changing the POE0 to POE3 pin input, depending on the output status of the high-current
pins (TIOC3B/PTE[6], TIOC3D/PTE[4], TIOC4A/PTE[3], TIOC4B/PTE[2], TIOC4C/PTE[1],
TIOC4D/PTE[0]). It can also simultaneously generate interrupt requests.
18.9.1
• Each of the POE0 to POE3 input pins can be set for falling edge, Pφ/8 × 16, Pφ/16 × 16, or
• High-current pins can be set to high-impedance state by POE0 to POE3 pin falling-edge or
• High-current pins can be set to high-impedance state when the high-current pin output levels
• Interrupts can be generated by input-level sampling or output-level comparison results.
