CMDQ_TRIG

Trigger to transfer the value of Command Index and

Argument registers into Command Index Queue and

Command Argument Queue registers. The trigger (transfer)

operation is only active when the value of this bit is high, and

the status of command queue is not busy (QBUSY_ST)

R/W

CMD_TCTL

Command Trigger Control

0: Start a new command immediately when the command

trigger (CMDQ_TRIG) bit was set

1: Only start a new command when the command trigger

(CMDQ_TRIG) bit was set and the previous response result

has been read

R/W

STB_CTL

Command Start Bit and Transmission Bit Control

0: The start bit and transmission bit of the SD/eMMC

command is automatically generated by H/W circuit

1: The start bit and transmission bit of the SD/eMMC

command refers to the STR_BIT and TRM_BIT of this control

STR_NIT

This register specifies the value of the start bit of SD/eMMC

command if STB_CTL bit is set to high. Otherwise, it is not

used

TRM_BIT

This register specifies the value of the transmission bit of

SD/eMMC command if STB_CTL bit is set to high.

Otherwise, it is not used
