Mode D
The direction of the data is determined by BDOEN. When BDOEN is true, BDIO[7:0] is input data
and is written when BDIEN is true and BDIBUSY is false. When BDOEN is false, BDIO[7:0] is output
data and is updated when both BDIEN and BDOAVAIL are true. Direction of data is also set by the
CFR (DMARW at 90h)
Mode E
The direction of the data is determined by the CFR (DMARW at 90h). When BDRW is true,
BDIO[7:0] is input data and is updated asynchronously with BDWR. When BDRW is false, BDIO[7:0]
is output data and is updated asynchronously with BDRD. In that case, BDIO[15:8] is high
impedance.
Mode F
Input data is written asynchronously with BDIEN input. Output data is updated asynchronously with
BDOEN input.
Mode G
The direction of the data is determined by BDOEN. When BDOEN is true, BDIO[15:0] is input data
and is written when BDIEN is true and BDIBUSY is false. When BDOEN is false, BDIO[15:0] is
output data and is updated when both BDIEN and BDOAVAIL are true. Direction of data is also set
by the CFR (DMARW at 90h)
Mode H
The direction of the data is determined by the CFR (DMARW at 90h). When BDRW is true,
BDIO[15:0] is input data and is asynchronously with BDWR. When BDRW is false, BDIO[15:0] is out-
put data and is updated asynchronously with BDRD.
9.1.1
Setting Active Signal
The polarity of BDIBUSY, BDOAVAIL, BDOEN, and BDIEN is determined by the BIBsyCtl, BOAvCtl, BOEnCtl and
BIEnCtl bits (90h, bits 12, 13, 14, and15, respectively). For each bit, 1 means active high and 0 means active low.

TSB43AA82A) (Modes A, D, and G)
In this mode, data is written synchronously with BDICLK input. Data direction is determined by BDOEN
(L: memory > TSB43AA82A).
