(1) IDDIO current is dependent on the electrical loading on the I/O pins.
(2) CPU2 must go into IDLE mode before CPU1 enters HALT mode.
(3) CPU2 must go into reset/IDLE/STANDBY mode before CPU1 enters HIBERNATE mode.
(4) MAX: Vmax, 125°C
(5) TYP: Vnom, 30°C
(6) The following is executed in a loop on CPU1:
- All of the communication peripherals are exercised in loop-back mode: CAN-A to CAN-B; SPI-A to SPI-C; SCI-A to SCI-D; I2C-A to I2C-B; McBSP-A to McBSP-B; USB
- SDFM1 to SDFM4 active
- ePWM1 to ePWM12 generate 400-kHz PWM output on 24 pins
- CPU TIMERs active
- DMA does 32-bit burst transfers
- CLA1 does multiply-accumulate tasks
- All ADCs perform continuous conversion
- All DACs ramp voltage up/down at 150 kHz
- CMPSS1 to CMPSS8 active
The following is executed in a loop on CPU2:
- CPU TIMERs active
- CLA1 does multiply-accumulate tasks
- VCU does complex multiply/accumulate with parallel load
- TMU calculates a cosine
- FPU does multiply/accumulate with parallel load
