These bits are always read as 0. The write value
should always be 0.
High-Z Memory Control
Specifies the pin state in software standby mode for
A25 to A0, BS, CSn, CS2x, RD/WR, WEn/DQMxx/AH,
RD, and FRAME. At bus-released state, these pin are
high-impedance states regardless of the setting value
of the HIZMEM bit.
0: High impedance in software standby mode.
1: Driven in software standby mode
High-Z Control
Specifies the state in software standby mode and bus-
released state for CKIO, CKE, RASU, RASL, CASU,
and CASL.
0: High impedance in software standby mode and bus-
