RP0H

Address:

0xF108h / 84h ESFR

Reset:

0x--XXh

Type:

RDYENx

READY Input Enable

0: External bus cycle is controlled by bit field MCTC only

1: External bus cycle is controlled by the READY input signal

RDYPOLx

Ready Active Level Control

0: Active level on the READY pin is low, bus cycle terminates with a ‘0’ on READY

pin,

1: Active level on the READY pin is high, bus cycle terminates with a ‘1’ on READY

pin.

CSRENx

Read Chip Select Enable

0: The CS signal is independent of the read command (RD)

1: The CS signal is generated for the duration of the read command

CSWENx

Write Chip Select Enable

0: The CS signal is independent of the write command (WR,WRL,WRH)

1: The CS signal is generated for the duration of the write command

R (1)(2)

RP0H.7 to RP0H.5 bits are loaded only during a long hardware reset. As pull-up resistors are active on

each Port P0H pins during reset, RP0H default value is "FFh"

These bits are set according to Port 0 configuration during any reset sequence.

R(2)

WRC

Write Configuration Control

0: Pin WR acts as WRL, pin BHE acts as WRH

1: Pins WR and BHE retain their normal function

CSSEL

Chip Select Line Selection (Number of active CS outputs)

00: 3 CS lines: CS2...CS0

01: 2 CS lines: CS1...CS0

10: No CS lines at all

11: 5 CS lines: CS4...CS0 (Default without pull-downs)

SALSEL

Segment Address Line Selection (Number of active segment address outputs)

00: 4-bit segment address: A19...A16

01: No segment address lines at all

10: 8-bit segment address: A23...A16

11: 2-bit segment address: A17...A16 (Default without pull-downs)
