Register function
The MONERS Register is a read-only register. The write access to this register is ignored. If a transfer
error occurs, details of that error are recorded in the MONERS Register. Details of an error can be
checked by referring to the MONERS Register. If MONER:EST indicates that an error has occurred, the
DSTC can generate an ERINT interrupt. If the ERINTE bit is set to "1", the ERINT interrupt signal for the
NVIC is asserted. The values of the MONERS Register and the ERINT interrupt can be cleared by
issuing an ERCLR command to the CMD Register.
For details of the contents of MONERS register, see "3.2.8 MONERS Register "
bit[2:0] EST[2:0] (Error status)
EST indicates details of an error that has occurred. In the case of EST ≠ 000, even if a new transfer error
occurs, DESP keeps details of the previous transfer error. ESTOP is cleared to "000" by the ERCLR
command.
