Access Type:
• CLKDIV: Clock Divider
Multimedia Card Interface clock (MCCK or MCI_CK) is Master Clock (MCK) divided by (2*(CLKDIV+1)).
• PWSDIV: Power Saving Divider
Multimedia Card Interface clock is divided by 2
Warning: This value must be different from 0 before enabling the Power Save Mode in the MCI_CR (MCI_PWSEN bit).
• RDPROOF Read Proof Enable
Enabling Read Proof allows to stop the MCI Clock during read access if the internal FIFO is full. This will guarantee data
integrity, not bandwidth.
0 = Disables Read Proof.
1 = Enables Read Proof.
• WRPROOF Write Proof Enable
Enabling Write Proof allows to stop the MCI Clock during write access if the internal FIFO is full. This will guarantee data
integrity, not bandwidth.
0 = Disables Write Proof.
1 = Enables Write Proof.
• PDCFBYTE: PDC Force Byte Transfer
Enabling PDC Force Byte Transfer allows the PDC to manage with internal byte transfers, so that transfer of blocks with a
size different from modulo 4 can be supported.
Warning: BLKLEN value depends on PDCFBYTE.
0 = Disables PDC Force Byte Transfer. PDC type of transfer are in words.
1 = Enables PDC Force Byte Transfer. PDC type of transfer are in bytes.
• PDCPADV: PDC Padding Value
0 = 0x00 value is used when padding data in write transfer (not only PDC transfer).
1 = 0xFF value is used when padding data in write transfer (not only PDC transfer).
