(1) I_DDIO current is dependent on the electrical loading on the I/O pins.
(2) I_DDA18 includes current into V_DD1A18 and V_DD2A18 pins. In order to realize the I_DDA18 currents shown for IDLE, STANDBY, and HALT,
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
(3) I_DDA33 includes current into V_DDA2 and V_DDAIO pins.
(4) The TYP numbers are applicable over room temperature and nominal voltage.
(5) When the identical code is run off SARAM, I_DD would increase as the code operates with zero wait states.
(6) The following is done in a loop:
• Data is continuously transmitted out of the SCI-A, SCI-B, SPI-A, McBSP-A, and eCAN-A ports.
• Floating-point multiplication and addition are performed.
• Watchdog is reset.
• ADC is performing continuous conversion. Data from ADC is transferred to SARAM through the DMA.
• 32-bit read/write of the XINTF is performed.
• GPIO19 is toggled.
