State
Clock Output — This pin outputs a buffered clock signal. Using
the SIM CLKO Select Register (SIM_CLKOSR), this pin can be
programmed as any of the following: disabled, CLK_MSTR
(system clock), IPBus clock, oscillator output, prescaler clock and
postscaler clock. Other signals are also available for test purposes.
See
Address Bus — A0 - A5 specify six of the address lines for
external program or data memory accesses.
Depending upon the state of the DRV bit in the EMI bus control
register (BCR), A0 - A5 and EMI control signals 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 A GPIO — These six GPIO pins can be individually
programmed as input or output pins.
After reset, the default state is Address Bus.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOA_PUR register.
Example: GPIOA8, clear bit 8 in the GPIOA_PUR register.
