Bits 23:16 – MAXCUR18V[7:0] Maximum Current for 1.8V
This field indicates the maximum current capability for 1.8V voltage. This value is meaningful only if
V18VSUP is set to 1 in CA0RCA1R. Reading MAXCUR18V at 0 means that the user must get
information via another method.
Imax
mA
= 4 × MAXCURR18
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 CA0R. Reading MAXCUR30V at 0 means that the user must get information via
another method.
Imax
mA
= 4 × MAXCURR30
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 CA0R. Reading MAXCUR33V at 0 means that the user must get information via
another method.
Imax
mA
= 4 × MAXCURR33
