Appendix B: Register Details
Register (sdio) Normal_interrupt_status_Error_interrupt_status
Register Normal_interrupt_status_Error_interrupt_status Details
Internal_Clock_Stable 1 ro 0x0 This bit is set to 1 when SD clock is stable after
writing to Internal Clock Enable in this register to
1. The SD Host Driver shall wait to set SD Clock
Enable until this bit is set to 1.
Note: This is useful when using PLL for a clock
oscillator that requires setup time.
1 - Ready
0 - Not Ready
Internal_Clock_Enable 0 rw 0x0 This bit is set to 0 when the HD is not using the
HC or the HC awaits a wakeup event. The HC
should stop its internal clock to go very low
power state. Still, registers shall be able to be read
and written. Clock starts to oscillate when this bit
is set to 1. When clock oscillation is stable, the HC
shall set Internal Clock Stable in this register to 1.
This bit shall not affect card detection.
1 - Oscillate
0 - Stop
