Notes
27.
With limited current capability
28.
5 V-CAN is ON in Debug Mode.
29.
I/O-0 and I/O-1, configured as an output high-side switch and ON in Normal Mode will remain ON in RESET, INIT or Normal
Request.
30.
I/O-0, configured as an output low-side switch and ON in Normal mode will turn OFF when entering Reset mode, resume
operation in Normal Mode.
31.
I/O-1, configured as an output low-side switch and ON in Normal mode will remain ON in RESET, INIT or Normal Request.
The 5 V-CAN default is ON when the device is powered-up and set in Debug Mode. It is fully controllable via the SPI command.
