Bit 4: SWAP - Host High-Low Swap
Setting this bit high causes the host access of high/low byte to be swapped.
Bit 3: RPEN - RAM Parity Check Logic Enable
Setting this bit high enables RAM-parity-check logic. If RPEN is high, RPINT (30h.3) becomes
active-high when a parity error is detected. RPINT and the interrupt can be cleared by writing any
value to register RAMCF (2Ah).
Bit 2-0: RTC[2:0] - External RAM Type Configuration Bits
The external RAM should be appropriately configured by these three bits according to its
specification. RTC[2:0] are de-activated by chip reset or host reset, but are not changed by firmware
reset.
