3.1
GPIO
Many pins have an optional GPIO function.
General purpose input is always active, regardless of state of pin.
General purpose output or primary output is determined by the appropriate setting of the Pin
Multiplex Control Registers, GPIO-FUNCTION, GPIO1-FUNCTION and PIN-CONFIG.
At Power-on reset, all pins are set to their primary function.
3.2
SCF5250 Bus Signals
These signals provide the external bus interface to the SCF5250 processor.
3.2.1
Address Bus
The address bus provides the address of the byte or most significant byte of the word or longword
being transferred. The address lines also serve as the DRAM address pins, providing multiplexed
row and column address signals.
Bits 23 down to 1 and 24 of the address are available. A24 is intended to be used with 256 Mbit
DRAM’s. Signals are named:
— A[23:1]
— A20/24
