PIC16F946 Limitations

PIC16F946, PIC16F917, PIC16F916, PIC16F914, PIC16F913

This device family does not require a header for debugging and none is available. Device limitations are as follows:

  • General Debug Limitations
  • General Programming Limitations
  • You cannot single step through an interrupt. Due to hardware restrictions, the debugger or emulator cannot jump to the interrupt vector memory location in Single Step mode.
  • Program memory standard Flash. Program memory, not enhanced Flash. You cannot program in Low Voltage mode (Vdd < 4.5 V). See the device programming specification for more information.
  • BF is cleared when SSPBUF is interrogated by software.
  • RCIF is cleared when RCREG is interrogated by software.
  • RBIF is cleared when PORT is interrogated by software.

Freeze on Halt Limitations

  • Freeze on Halt is not supported.
