7.5.2 Change from LC89058W-E to LC89057W-VF4A-E
7.5.2.1 When the INT pin is set to pull-down
• It is necessary to review the circuit pattern of the printed circuit board to change the pull-up resistor of pin 35 to the
• It is necessary to review the circuit pattern of the printed circuit board because the I/O setting of pin 48 differs from
• After the replacement, the RXOUT2 output of LC89057W-VF4A-E cannot be used.
7.5.2.2 When the INT pin is set to pull-up
• After the replacement, pins 44 to 47 can be used as general purpose I/O output function. However, it is necessary to
