11 | * To enable external serial I/O on a Freescale MPC 8323 SYS/MDS board, do | ||
12 | * this: | ||
13 | * | ||
14 | * 1) On chip U61, lift (disconnect) pins 21 (TXD) and 22 (RXD) from the board. | ||
15 | * 2) Solder a wire from U61-21 to P19A-23. P19 is a grid of pins on the board | ||
16 | * next to the serial ports. | ||
17 | * 3) Solder a wire from U61-22 to P19K-22. | ||
18 | * | ||
19 | * Note that there's a typo in the schematic. The board labels the last column | ||
20 | * of pins "P19K", but in the schematic, that column is called "P19J". So if | ||
21 | * you're going by the schematic, the pin is called "P19J-K22". | ||
