568 Freescale Semiconductor
Two cases with internal voltage regulator enabled and disabled must be considered:
1. Internal Voltage Regulator disabled
Which is the sum of all output currents on I/O ports associated with VDDX and VDDM.
For R
DSON
is valid:
respectively
2. Internal voltage regulator enabled
I
DDR
is the current shown in Table A-8 and not the overall current flowing into VDDR, which
additionally contains the current flowing into the external loads with output high.
Which is the sum of all output currents on I/O ports associated with VDDX and VDDR.
