All PWM pins are toggled at 200 kHz. All
I/O pins are left unconnected. XCLKOUT
is turned off. Pullups on output pins and
XINTF pins are disabled.

(1) The I
DD
numbers in this table are valid for the TMS320C28345 and TMS320C28343 devices only. For the TMS320C28341 device,
subtract the I
DD
current numbers for those peripherals that do not exist on this device (see Table 6-3) from the I
DD
current numbers
shown in this table.
(2) I
DDIO
current is dependent on the electrical loading on the I/O pins.
(3) 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.
• 32-bit read/write of the XINTF is performed.
• DMA channels 1 and 2 transfer data from SARAM to SARAM.
• GPIO19 is toggled.
(4) If a quartz crystal or ceramic resonator is used as the clock source, the HALT mode shuts down the internal oscillator.
NOTE
The I
DD
numbers in Table 6-2 are valid for the TMS320C28345 and TMS320C28343 devices
only. For the TMS320C28341 device, subtract the I
DD
current numbers for those peripherals
that do not exist on this device (see Table 6-3) from the I
DD
current numbers shown in
Table 6-2.
