Port B GPIO — These four GPIO pins can be programmed as
input or output pins.
Address Bus — A16 - A19 specify one 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–A23 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.
After reset, the startup state of GPIOB0 - 3 (GPIO or address)
is determined as a function of EXTBOOT, EMI_MODE and the
Flash security setting. See Table 4-4 for further information on
when this pin is configured as an address pin at reset. In all
cases, this state may be changed by writing to GPIOB_PER.
To deactivate the internal pull-up resistor, clear the appropriate
GPIO bit in the GPIOB_PUR register.

Clock Outputs — can be used to monitor the prescaler_clock,
SYS_CLK, SYS_CLK2 or oscillator_clock on GPIOB4 through
GPIOB7, respectively.
After reset, the default state is GPIO.
These pins can also be used to extend the external address
bus to its full length or to view any of several system clocks. In
these cases, the GPIO_B_PER can be used to individually
disable the GPIO. The CLKOSR register in the SIM ( see Part
6.5.7) can then be used to choose between address and clock
functions.
