Hi,

I am working on FS6500 SBC, I noticed an error when i try LPOFF_Auto_WU.

When I want to set the LPOFF_AUTO_WU bit ( call FS65_SetLowPowerMode(true) ), the GO_LPOFF bit is also set. It doesn't sleep, doesn't reset.

I changed line 14.

from

writeData = (response.readData & FS65_RW_M_VKAM_EN_MASK) | FS65_W_M_GO_LPOFF_LPOFF;

writeData = (response.readData & FS65_RW_M_VKAM_EN_MASK); // | FS65_W_M_GO_LPOFF_LPOFF;

Fixed FS65_SetLowPowerMode function.

fs65_status_t FS65_SetLowPowerMode(bool autoWU) { fs65_status_t status; /* Status variable. */ fs65_rx_data_t response; /* Response to the command. */ uint8_t writeData; /* Data to be updated. */ /* Read VKAM control state to preserve it. */ status = FS65_ReadRegister(FS65_M_MODE_ADDR, &response); if (status != fs65StatusOk) { return status; } /* Set previously read VKAM value to write data. */ writeData = (response.readData & FS65_RW_M_VKAM_EN_MASK); //| FS65_W_M_GO_LPOFF_LPOFF; /* Set LPOFF mode. */ writeData |= autoWU ? FS65_W_M_LPOFF_AUTO_WU_LPOFF : FS65_W_M_GO_LPOFF_LPOFF; return FS65_WriteRegister(FS65_M_MODE_ADDR, writeData, NULL); /* Write check is not performed because of entering LPOFF mode. */ }
