|
| Advantech default function is used |
| ||||||
|
|
| as external 16C954 solution IC IRQ. |
| ||||||
|
|
| The pin directly connects to PXA255 |
| ||||||
B44 | C954_IRQ | I | GPIO32 (A16 pin). If user doesn’t | No pulling | ||||||

| design 16C950 on CSB to expand |

|
| COM function, user could use this |
