Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7:6 | Reserved | R | 0 | This control is reserved and must not be changed from its default setting. |
5:4 | OCE Thres | R/W | 00 | OCE Threshold
00: Threshold is set to the default level specified in the electrical characteristics table. (Default) 01: Threshold is reduced to 75% of the evel specified in the electrical characteristics table. 10: Threshold is reduced to 50% of the evel specified in the electrical characteristics table. 11: Threshold is reduced to 25% of the evel specified in the electrical characteristics table. |
3 | CLKE | R | 0 | Clock Error Status
0: Clocks are valid and no error is currently detected. 1: A clock error is occuring (This error is non-latching, so intermittent clock errors will be cleared when clocks re-enter valid state and the device will resume normal operation automatically. This bit will likewise be cleared once normal operation resumes.). |
2 | OCE | R | 0 | Over Current Error Status
0: The output current levels of the speaker amplifier outputs are below the OCE threshold. 1: The DC offset level of the outputs has exceeded the OCE threshold, causing an error (This is a latching error and SPK_SD must be toggled after an OCE event for the device to resume normal operation. This bit will remain HIGH until SPK_SD is toggled.). |
1 | DCE | R | 0 | Output DC Error Status
0: The DC offset level of the speaker amplifier outputs are below the DCE threshold. 1: The DC offset level of the speaker amplifier outputs has exceeded the DCE threshold, causing an error (This is a latching error and SPK_SD must be toggled after an DCE event for the device to resume normal operation. This bit will remain HIGH until SPK_SD is toggled.). |
0 | OTE | R | 0 | Over-Temperature Error Status
0: The temperature of the die is below the OTE threshold. 1: The temperature of the die has exceeded the level specified in the electrical characteristics table. (This is a latching error and SPK_SD must be toggled for the device to resume normal operation. This bit will remain HIGH until SPK_SD is toggled.). |
