5.4.1 G3-PLC Coupling Configuration
In the G3-PLC firmware packages provided by Microchip, the transmission coupling configuration parameters for the reference designs are located in the path: asf\thirdparty\g3\phy\atpl360\coup_tx_config\coup_params.
Each project applies the appropriate values for the corresponding PLC device and board.
The PL360 parameters related to the transmission coupling configuration are described
in:
- ATPL360_REG_MAX_RMS_TABLE_HI (0x4025)
- ATPL360_REG_MAX_RMS_TABLE_VLO (0x4026)
- ATPL360_REG_THRESHOLDS_TABLE_HI (0x4027)
- ATPL360_REG_THRESHOLDS_TABLE_LO (0x4028)
- ATPL360_REG_THRESHOLDS_TABLE_VLO (0x4029)
- ATPL360_REG_PREDIST_COEF_TABLE_HI (0x402A)
- ATPL360_REG_PREDIST_COEF_TABLE_LO (0x402B)
- ATPL360_REG_PREDIST_COEF_TABLE_VLO (0x402C)
- ATPL360_REG_GAIN_TABLE_HI (0x402D)
- ATPL360_REG_GAIN_TABLE_LO (0x402E)
- ATPL360_REG_GAIN_TABLE_VLO (0x402F)
- ATPL360_REG_DACC_TABLE_CFG (0x4030)
- ATPL360_REG_PLC_IC_DRIVER_CFG (0x4045)
The default values of these parameters correspond to the PL360MB evaluation kit with the
appropriate coupling board for the used band:
- CENELEC-A: PLCOUP007
- CENELEC-B: PLCOUP014
- FCC: PLCOUP006
- ARIB: PLCOUP006
