The main page for the Teesny 4.0 (https://www.pjrc.com/store/teensy40.html) states that is has 2 CAN interfaces. The pinout diagram shows CTX1/CRX1, CTX2/CRX2 and underneath CTX3/CRX3. Are there 2 or 3 CAN interfaces?
Also, CTX1/CRX1 are shown as being on pins 22/23 and 11/13. Why is this one doubled up?
