Table 18-39. SD_IE Register Field Descriptions (continued)
Bit Field Type Reset Description
18 CEB_ENABLE R/W 0h
Command end bit error interrupt enable
0x0 = Masked
0x1 = Enabled
17 CCRC_ENABLE R/W 0h
Command CRC error interrupt enable
0x0 = Masked
0x1 = Enabled
16 CTO_ENABLE R/W 0h
Command timeout error interrupt enable
0x0 = Masked
0x1 = Enabled
15 NULL R 0h Fixed to 0.
The host driver shall control error interrupts using the Error Interrupt
Signal Enable register.
Writes to this bit are ignored.
14-11 Reserved R 0h
10 BSR_ENABLE R/W 0h
Boot Status Interrupt Enable A write to this register when
SD_CON[BOOT] is cleared to 0 is ignored.
0x0 = Masked
0x1 = Enabled
9 OBI_ENABLE R/W 0h
Out-of-band interrupt enable A write to this register when
SD_CON[14] OBIE is cleared to 0 is ignored.
0x0 = Masked
0x1 = Enabled
8 CIRQ_ENABLE R/W 0h Card interrupt enable.
A clear of this bit also clears the corresponding status bit.
During
1-bit mode, if the interrupt routine does not remove the source of a
card interrupt in the SDIO card, the status bit is reasserted when this
bit is set to 1.
This bit must be set to 1 when entering in smart idle mode to enable
system to identity wake-up event and to allow controller to clear
internal wake-up source.
0x0 = Masked
0x1 = Enabled
7 CREM_ENABLE R/W 0h Card Removal interrupt Enable This bit must be set to 1 when
entering in smart idle mode to enable system to identity wake-up
event and to allow controller to clear internal wake-up source.
0x0 = Masked
0x1 = Enabled
6 CINS_ENABLE R/W 0h Card Insertion interrupt Enable This bit must be set to 1 when
entering in smart idle mode to enable system to identity wake-up
event and to allow controller to clear internal wake-up source.
0x0 = Masked
0x1 = Enabled
5 BRR_ENABLE R/W 0h
Buffer read ready interrupt enable
0x0 = Masked
0x1 = Enabled
4 BWR_ENABLE R/W 0h
Buffer write ready interrupt enable
0x0 = Masked
0x1 = Enabled
3 DMA_ENABLE R/W 0h
DMA interrupt enable
0x0 = Masked
0x1 = Enable
