                              |   | Single power supply can operate from 2.4V to 5.5V at 8MHz, or from 3.6V to 5.5V at 16MHz. |  
                              |   | Program ROM can be up to 192k x 12-bit. (00000H~2FFFFH, 3 banks) |  
                              |   | Data SRAM can be up to 448 x 4-bit. (20H~FFH per page, total 2 pages) |  
                              |   | There are total 14 I/O pins, PRA and PRB[0,1,3]. Each pin of all ports can be wake-up port when
they are configured as input or IO mode. |  
                              |   | There are two kinds of clock sources in the device of AM4F.
a). Resistor mode (RM).
b). High frequency crystal mode (HM). |  |
