INDUSTRIAL TEMPERATURE RANGE
GREG10: SB1 Direction Control and SB1 Status/Control Data, Read/Write (29H/A9H)
The SB1 direction control bits SB1C[3:0] in this register determine the directions of the SB1 pins of Channel 4 to Channel 1 respectively.
SB1C[0] = 0:
the SB1 pin of Channel 1 is configured as input (default);
SB1C[0] = 1:
the SB1 pin of Channel 1 is configured as output;
SB1C[1] = 0:
the SB1 pin of Channel 2 is configured as input (default);
SB1C[1] = 1:
the SB1 pin of Channel 2 is configured as output;
SB1C[2] = 0:
the SB1 pin of Channel 3 is configured as input (default);
SB1C[2] = 1:
the SB1 pin of Channel 3 is configured as output;
SB1C[3] = 0:
the SB1 pin of Channel 4 is configured as input (default);
SB1C[3] = 1:
the SB1 pin of Channel 4 is configured as output.
When the SB1 pins of Channel 1 to Channel 4 are configured as inputs, the SB1[0] to SB1[3] bits contain the status of these four SB1
pins respectively. When the SB1 pins of Channel 1 to Channel 4 are configured as outputs, the control data is written to these four SB1
pins via the SB1[0] to SB1[3] bits respectively.
GREG11: SB2 Direction Control and SB2 Status/Control Data, Read/Write (2AH/AAH)
The SB2 direction control bits SB2C[3:0] in this register determine the directions of the SB2 pins of Channel 4 to Channel 1 respectively.
SB2C[0] = 0:
the SB2 pin of Channel 1 is configured as input (default);
SB2C[0] = 1:
the SB2 pin of Channel 1 is configured as output;
SB2C[1] = 0:
the SB2 pin of Channel 2 is configured as input (default);
SB2C[1] = 1:
the SB2 pin of Channel 2 is configured as output;
SB2C[2] = 0:
the SB2 pin of Channel 3 is configured as input (default);
SB2C[2] = 1:
the SB2 pin of Channel 3 is configured as output;
SB2C[3] = 0:
the SB2 pin of Channel 4 is configured as input (default);
SB2C[3] = 1:
the SB2 pin of Channel 4 is configured as output.
When the SB2 pins of Channel 1 to Channel 4 are configured as inputs, the SB2[0] to SB2[3] bits contain the status of these four SB2
pins respectively. When the SB2 pins of Channel 1 to Channel 4 are configured as outputs, the control data is written to these four SB2
pins via the SB2[0] to SB2[3] bits respectively.
GREG12: SB3 Direction Control and SB3 Status/Control Data, Read/Write (2BH/ABH)
The SB3 direction control bits SB3C[3:0] in this register determine the directions of the SB3 pins of Channel 4 to Channel 1 respectively.
SB3C[0] = 0:
the SB3 pin of Channel 1 is configured as input (default);
SB3C[0] = 1:
the SB3 pin of Channel 1 is configured as output;
SB3C[1] = 0:
the SB3 pin of Channel 2 is configured as input (default);
SB3C[1] = 1:
the SB3 pin of Channel 2 is configured as output;
SB3C[2] = 0:
the SB3 pin of Channel 3 is configured as input (default);
SB3C[2] = 1:
the SB3 pin of Channel 3 is configured as output;
SB3C[3] = 0:
the SB3 pin of Channel 4 is configured as input (default);
SB3C[3] = 1:
the SB3 pin of Channel 4 is configured as output.
When the SB3 pins of Channel 1 to Channel 4 are configured as inputs, the SB3[0] to SB3[3] bits contain the status of these four SB3
