Description

⎯

Reserved

These bits are always read as 0. The write value

should always be 0.

HIZCKIO

R/W

High-Z CK Control

Specifies the state in CK standby mode and when bus

mastership is released.

0: CK is in high impedance state in standby mode and

bus-released state.

1: CK is driven in standby mode and bus-released

state.

HIZMEM

R/W

High-Z Memory Control

Specifies the pin state in standby mode for A25 to A0,

BS, CSn, RD/WR, WEn/DQMxx, AH, and RD. At bus-

released state, these pins are in high-impedance state

regardless of the setting value of the HIZMEM bit.

0: High impedance in standby mode.

1: Driven in standby mode

HIZCNT

R/W

High-Z Control

Specifies the state in standby mode and bus-released

state for CKE,

RASL, and CASL.

0: CKE,

RASL, and CASL are in high-impedance state

in standby mode and bus-released state.

1: CKE,

RASL, and CASL are driven in standby mode

and bus-released state.
