9.3.7 Peripheral I/O
This mode enables the microcontroller to read or write to a peripheral though Port A. When
there is no read/write operation, Port A is tri-stated. One of the applications of Peripheral
I/O is in a DMA based design.
t Configuration
1. Declare the pins used as pheripheral I/O in the ABEL file.
2. Write logic equations for PSEL0 and PSEL1.
3. Write a “1” to the PIO bit in the VM Register to activate the Peripheral I/O operation.
See the section on Peripheral I/O for a detailed description.
9.3.8 Open Drain Outputs
This mode enables the user to configure Ports C and D pins as open drain outputs. CMOS
output is the default configuration. Writing “1” to the corresponding bit in the Open Drain
Register changes the pin to open drain output.
Table 12. Operating Modes of the I/O Ports
Table 12 summarizes the operating modes of the I/O ports. Not all the functions are
available to every port.
