Section 13 Bus State Controller (BSC)
Bit 16—DMAC Burst Mode Transfer Priority Setting (DMABST) (SH7750R Only):
Specifies the priority of burst mode transfers by the DMAC. When OFF, the priority is as follows:
bus privilege released, refresh, DMAC, CPU. When ON, the bus privileges are released and
refresh operations are not performed until the end of the DMAC's burst transfer. This bit is
initialized at a power-on reset.

Bit 15—High Impedance Control (HIZMEM): Specifies the state of address and other signals
(A[25:0], BS, CSn, RD/WR, CE2A, CE2B) in software standby mode.

Description
The A[25:0], BS, CSn, RD/WR, CE2A, and CE2B signals go to high-
impedance (High-Z) in standby mode and when the bus is released
The A[25:0], BS, CSn, RD/WR, CE2A, and CE2B signals are driven in
standby mode. When the bus is released, they go to high-impedance.
Description
The RAS, RAS2, WEn/CASn/DQMn, RD/CASS/FRAME, and RD2 signals
go to high-impedance (High-Z) in standby mode and when the bus is
released
The RAS, RAS2, WEn/CASn/DQMn, RD/CASS/FRAME, and RD2 signals
are driven in standby mode and when the bus is released
