23.20 Flash Memory Programming Using Boot Program

When programming the internal flash memory using boot program, be careful about the pins state and
connection as follows.

23.20.1 Programming Using Serial I/O Mode

CTX0 pin : This pin automatically outputs "H" level.
CRX0 pin : Connect to CAN transceiver or connect via resister to VCC (pull-up)
Figure 23.9 shows a pin connection example for programming using serial I/O mode.

23.20.2 Programming Using CAN I/O Mode

_________
RTS1 pin : This pin automatically outputs "H" and "L" level.
Figure 23.10 shows a pin connection example for programming using CAN I/O mode.
