 Flash memory error detection

Set the Flash memory error detection with the ROMEN bit of the SAFE command. It is possible to detect two kinds of

errors.

① Flash memory read data error

When an error is detected in the read data from the flash memory, the error bit (ROMERR) is set to "1". At the same time,

playback of the corresponding channel is stopped.

If the error bit (ROMERR) is set to "1" after the PUP command and before the PLAY command or START command starts

playback, this LSI may have error at the time of start. In such cases, initialize this LSI by moving the LSI to the power-down

mode by resetting the LSI by the RESETB pin or by using PDWN command.

② Access outside the flash memory address range

If the flash memory is accessed outside the flash memory address range, an error is detected and the error bit (ROMERR) is

set to "1".

At the same time, playback of the corresponding channel is stopped.

Error bit (ROMERR) can be read with RDERR command. Error bit (ROMERR) can be cleared by ERRCL command.
