3.2 Reset RX Detect State Machine

The RX Detect State Machine may be manually reset for all channels.

Table 3-4 Sequence to Reset RX Detect State Machine
StepRegister SetOperationRegister Address [HEX]Register Value [HEX]Write Mask [HEX]Comment
1RX_DET_CTRL2 RegisterWrite0x090x040x04Set RX Detect Reset bit to: 1 (Reset RX Detect State Machine)
2RX_DET_CTRL2 RegisterWrite0x090x000x04Set RX Detect Reset bit to: 0 (Clear set bit)

Assuming 0x18 is the I2C/SMBus addresses for the RX_DET_CTRL2 Register, the following is the XML batch script of the sequence in :

<i2c_write addr="0x18" count="0" radix"16">09 04</i2c_write>
<i2c_write addr="0x18" count="0" radix"16">09 00</i2c_write>
