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.
J
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.
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.
