PCM5121: PSTM status

Part Number: PCM5121

Hi

Table 113 in the datasheet offers explanation of PSTM, but it is not in detailed.

 

Does PSTM status represent error status?

If these bit offer error status, we should avoid these error conditions.

Is it possible to show us what each bit of PSTM status means?

BestRegards

    Hi Usui-san,

    The PSTM status is really the just the power supply/boot status of the device. These do not all represent errors. Really the only 'error' condition described by the table is 0b'0110, which indicates that there is too low of a load on the output of the DAC. This could be helpful in diagnosing issue in system. The other states mostly indicate what state the device is in during power on or exiting power down mode. Generally, I would not monitor this register for error, but possibly use it for debug.

    Thanks!
