Some parametric limits are subject to
[Data Bus Buffer Status Register 0, 1 (DBBS0, DBBS1)]
0049
16
, 004D
16
The data bus buffer status registers 0, 1 consist of eight bits each.
Bits 0, 1, and 3 are read-only bits and indicate the status of the
data bus buffer. Bits 2, 4, 5, 6, and 7 are user definable flags
which can be programed, and can be read/written. The host CPU
can only read this register when the A
0
pin is set to
“
H
”
.
Bit 0: Output buffer full flag OBF
0
, OBF
1
When writing data to the output data bus buffer, this flag is set to
“
1
”
. When reading the output data bus buffer from the host CPU,
this flag is cleared to
“
0
”
.
Bit 1: Input buffer full flag IBF
0
, IBF
1
When writing data from the host CPU to the input data bus
buffer, this flag is set to
“
1
”
. When reading the input data bus
buffer from the slave CPU side, this flag is are cleared to
“
0
”
.
Bit 3: A0 flag A
00
, A
01
When writing data from the host CPU to the input data bus
buffer, the level of the A
0
pin is latched.
[Input Data Bus Buffer Registers 0, 1 (DBBIN
0
, DBBIN
1
)]
0048
16
, 004C
16
Data on the data bus is latched to DBBIN
0
or DBBIN
1
by writing
request from the host CPU. Data of DBBINs can be read from the
Data Bus Buffer Registers (address 0048
16
or 004C
16
) on the
SFR area.
[Output Data Bus Buffer Registers 0, 1 (DBBOUT
0
,
DBBOUT
1
)] 0048
16
, 004C
16
When writing data to the Data Bus Buffer Registers (address
0048
16
or 004C
16
) on the SFR area, data is set to DBBOUT
0
or
DBBOUT
1
. Data of DBBOUTs is output onto the data bus by per-
forming the reading request from the host CPU when the A
0
pin is
set to
“
L
