5. The minimum pulse width to wake up the MSCAN module is guaranteed by design but not tested.
1. V
2. The external system error caused by input leakage current is approximately equal to the product of R source and input
3. Source impedances greater than 10 kΩ adversely affect internal RC charging time during input sampling.
