Bits 15:8 – MAXCUR30V[7:0] Maximum Current for 3.0V
This field indicates the maximum current capability for 3.0V voltage. This value is meaningful only if V30VSUP is set to 1 in SDHC_CA0R. Reading MAXCUR30V at 0 means that the user must get information via another method.
Bits 7:0 – MAXCUR33V[7:0] Maximum Current for 3.3V
This field indicates the maximum current capability for 3.3V voltage. This value is meaningful only if V33VSUP is set to 1 in SDHC_CA0R. Reading MAXCUR33V at 0 means that the user must get information via another method.
