56F8366 Technical Data, Rev. 6
Data Bus — D7 - D14 specify part of the data for external program
or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus control
register (BCR), D7 - D14 are tri-stated when the external bus is
inactive.
Most designs will want to change the DRV state to DRV = 1 instead of
using the default setting.
Port F GPIO — These eight GPIO pins can be individually
programmed as input or output pins.
At reset, these pins default to Data Bus functionality.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOF_PUR register.
Example: GPIOF0, clear bit 0 in the GPIOF_PUR register.
Data Bus — D15 specifies part of the data for external program or
data memory accesses.
Most designs will want to change the DRV state to DRV = 1 instead of
using the default setting.
Port F GPIO — This GPIO pin can be individually programmed as
an input or output pin.
At reset, this pin defaults to the data bus function.
To deactivate the internal pull-up resistor, set bit 8 in the
GPIOF_PUR register.
