Interrupt At Block Gap 

This bit is valid only in 4-bit mode of the SDIO card and selects a sample point in the 
interrupt cycle. Setting to 1 enables interrupt detection at the block gap for a multiple 
block transfer. Setting to 0 disables interrupt detection during a multiple block transfer. 
If the SD card cannot signal an interrupt during a multiple block transfer, this bit must 
be set to 0. When the Host Driver detects an SD card insertion, it will set this bit 
according to the CCCR of the SDIO card. (RW)  
‘1’ = Enabled  

‘0’ = Disabled  

0 

 [2] 

Read Wait Control 

The read wait function is optional for SDIO cards. If the card supports read wait, set 
this bit to enable use of the read wait protocol to stop read data using the 

DAT

[2] line. 

Otherwise the Host Controller has to stop the SD Clock to hold read data, which 
restricts commands generation. When the Host Driver detects an SD card insertion, it 
will set this bit according to the CCCR of the SDIO card. If the card does not support 
read wait, this bit will never be set to 1 otherwise 

DAT 

line conflict may occur. If this 

bit is set to 0, Suspend/Resume cannot be supported. (RW) 
‘1’ = Enable Read Wait Control  

‘0’ = Disable Read Wait Control  

0 

 [1] 

Continue Request 

This bit is used to restart a transaction which was stopped using the 

Stop At Block 

Gap Request

. To cancel stop at the block gap, set 

Stop At Block Gap Request 

to 0 

and set this bit 1 to restart the transfer.  
The Host Controller automatically clears this bit in either of the following cases: 
(1) If a read transaction, the 

DAT Line Active 

changes from 0 to 1 as a read 

transaction restarts. 
(2) If a write transaction, the 

Write Transfer Active 

changes from 0 to 1 as the write 

transaction restarts.  
Therefore it is not necessary for Host Driver to set this bit to 0. If 

Stop At Block Gap 

Request 

is set to 1, any write to this bit is ignored. (RWAC) 

‘1’ = Restart  

‘0’ = Not affect   

0 

 [0] 

Stop At Block Gap Request 

This bit is used to stop executing a transaction at the next block gap for both DMA and 
non-DMA transfers. Until the 

Transfer Complete 

is set to 1, indicating a transfer 

completion the Host Driver will leave this bit set to 1.  
Clearing both the 

Stop At Block Gap Request 

and 

Continue Request 

will not cause 

the transaction to restart. Read Wait is used to stop the read transaction at the block
