4.5.5 Response end interrupt
+ Interrupt Assert Condition
After a response received from an SD card, an interrupt is generated. Regarding R1b response type, after busy
released from an SD card, an interrupt is generated.
<In the case of normal command>
<In the case of R1b command>
+ Factor Evaluation Method
In the case of SD memory Card, the SREP bit(D0) of SD Card Status Register(Offset:01C-01Dh) is set to "1". In
the case of SDIO Card, the SREP bit(D0) of SD Card Status Register(Offset:11C-11Dh) is set to "1".
+De-asserting Method
SD memory Card
(1) "0" is written into the SREP bit(D0) of SD Card Status Register(Offset:01C-01Dh).
(2) "1" is written into the MREP bit(D0) 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).
SDIO Card
(1) "0" is written into the SREP bit(D0) of SD Card Status Register(Offset:11C-11Dh)
(2) "1" is written into the MREP bit(D0) of SD Interrupt Mask Register(Offset:120-123h).
(3) Hardware reset by #PCLR = “0”.
(4) Software reset by writing "0" into the SRST bit(D0) of SD Software Reset Register(Offset:1E0h).
