+ Factor Evaluation Method
The SCOT bit(D3) of SD Card Status Register(Offset:01C-01Dh) is set to "1".
+De-asserting Method
(1) "0" is written into the SCOT bit(D3) of SD Card Status Register(Offset:01C-01Dh).
(2) "1" is written into the MCOT bit(D3) of SD Interrupt Mask Register(Offset:020-023h).
(3) Hardware reset by #PCLR = “0”.
(4) Software reset by writing "0" into the SRST bit(D0) of SD Software Reset Register(Offset:0E0h).
4.5.3 Buffer write enable interrupt
+ Interrupt Assert Condition
When data to be transmitted to the card becomes available for the internal buffer, SD Data Port
Register(Offset:030-031h, 130-131h), to be written for a write command, an interrupt is generated.
+ Factor Evaluation Method
In the case of SD memory Card, the SBWE bit(D9) of SD Buffer Control & Error Status Register(Offset:01E-
01Fh) is set to "1". In the case of SDIO Card, the SBWE bit(D9) of SD Buffer Control & Error Status
Register(Offset:11E-11Fh) is set to "1".
