Create a dedicated CAN communication sheet named CAN_COMM.

Design CAN FD x2 interface for URIMKOREA UR-150K control board.

Requirements:

1. CAN Channel 1:
- Isolated CAN FD transceiver
- Compatible with STM32H743 FDCAN
- 120 ohm termination resistor selectable by jumper
- TVS/ESD protection
- Common mode choke
- External connector
- Isolated 5V power for bus side
- Logic side 3.3V interface

2. CAN Channel 2:
- Isolated CAN FD transceiver
- Compatible with STM32H743 FDCAN
- 120 ohm termination resistor selectable by jumper
- TVS/ESD protection
- Common mode choke
- External connector
- Isolated 5V power for bus side
- Logic side 3.3V interface

3. Isolation:
- Clear isolation barrier between MCU side and field bus side
- Separate net names:
  CAN1_TX
  CAN1_RX
  CAN1_H
  CAN1_L
  CAN2_TX
  CAN2_RX
  CAN2_H
  CAN2_L

4. Recommended parts:
- Use ISO1042 or ISO1050 family if available
- Use industrial-grade ESD/TVS protection

Requirements:
- Generate schematic only
- Do not modify MCU, POWER, or ETH sheets
- Do not create PCB layout
- Add design notes for CAN sheet
