• Manufacturer Part Number: DSPIC30F4012
• Description: Dspic30f4011/4012 Enhanced Flash 16-bit Digital Signal Controller
• Manufacturer: Microchip Technology Inc.

Table 1-1 provides a brief description of the device I/O
pinout and the functions that are multiplexed to a port
pin. Multiple functions may exist on one port pin. When
multiplexing occurs, the peripheral module’s functional
requirements may force an override of the data
direction of the port pin.
