WAKEUP CONTROL REGISTER
This register is mandatory for the Host Controller, but wakeup functionality depends on the Host Controller system
hardware and software. The Host Driver maintains voltage on the SD Bus, by setting SD Bus Power to 1 in the
Power Control register, when wakeup event via Card Interrupt is desired.
