applies to output-only pins, indicating off-state (hi-Z) output leakage current.
Assumes the following conditions: 50% CPU utilization; DDR2 at 20% utilization (250 MHz), 50% writes, 32 bits, 50% bit switching;
EMIFA at 40% utilization (133 MHz), 50% writes, 64 bits, 50% bit switching; McBSP0/1 at 100 MHz, 10% utilization, 50% switching;
VCP2 at 50% utilization; TCP2 at 20% utilization; EMAC, 1000 Mbps, RGMII, 50% utilization, 50% switching; SRIO 3.125, 4 lanes, 50%
utilization, 50% switching; One 100-MHz Timer at 10% utilization; device configured for HPI32 mode, 50 MBps, 30% utilization, 50%
writes, 32, 50% switching, with pull-up resistors on HPI pins; room temperature (25
