3.3 Set SEL Input

The Input SEL may be manually set to select Port A or Port B.

Table 3-5 Sequence to set Port SEL
StepRegister SetOperationRegister Address [HEX]Register Value [HEX]Write Mask [HEX]Comment
1Select Value Field RegisterWrite0x0E0x040x04Set to overwrite SEL pin input
2Select Value Field RegisterWrite0x0F0x040x04Set SEL_VAL bit to select Port B (Default 0 = Port A)

Assuming 0x18 is the I2C/SMBus addresses for the Select Value Field Register, the following is the XML batch script of the sequence in :

<i2c_write addr="0x18" count="0" radix"16">0E 04</i2c_write>
<i2c_write addr="0x18" count="0" radix"16">0F 04</i2c_write>
