Chapter 3 Port Integration Module (PIM9E128V1)
3.3.1
Port AD is associated with the analog-to-digital converter (ATD) and keyboard wake-up (KWU)
interrupts. Each pin is assigned to these modules according to the following priority: ATD > KWU >
general-purpose I/O.
For the pins of port AD to be used as inputs, the corresponding bits of the ATDDIEN0 and ATDDIEN1
registers in the ATD module must be set to 1 (digital input buffer is enabled). The ATDDIEN0 and
ATDDIEN1 registers do not affect the port AD pins when they are configured as outputs.
