Appendix B: Register Details
Command_Index_Erro
r
19 wtc 0x0 Occurs if a Command Index error occurs in the
Command Response.
0 - No Error
1 - Error
Command_End_Bit_Er
ror
18 wtc 0x0 Occurs when detecting that the end bit of a
command response is 0.
0 - No Error
1 - End Bit Error Generated
Command_CRC_Error 17 wtc 0x0 Command CRC Error is generated in two cases.
1. If a response is returned and the Command
Timeout Error is set to 0, this bit is set to 1 when
detecting a CRT error in the command response
2. The HC detects a CMD line conflict by
monitoring the CMD line when a command is
issued. If the HC drives the CMD line to 1 level,
but detects 0 level on the CMD line at the next
SDCLK edge, then the HC shall abort the
command (Stop driving CMD line) and set this bit
to 1. The Command Timeout Error shall also be
set to 1 to distinguish CMD line conflict.
0 - No Error
1 - CRC Error Generated
Command_Timeout_Er
ror
16 wtc 0x0 Occurs only if the no response is returned within
64 SDCLK cycles from the end bit of the
command. If the HC detects a CMD line conflict,
in which case Command CRC Error shall also be
set. This bit shall be set without waiting for 64
SDCLK cycles because the command will be
aborted by the HC.
0 - No Error
1 - Timeout
Error_Interrupt 15 ro 0x0 If any of the bits in the Error Interrupt Status
Register are set, then this bit is set. Therefore the
HD can test for an error by checking this bit first.
0 - No Error.
1 - Error.
reserved 14:11 ro 0x0 Reserved
Boot_terminate_Interru
pt
10 wtc 0x0 This status is set if the boot operation get
terminated
0 - Boot operation is not terminated.
1 - Boot operation is terminated
Boot_ack_rcv 9 wtc 0x0 This status is set if the boot acknowledge is
received from device.
0 - Boot ack is not received.
1 - Boot ack is received.
