How to debug chip with 2 uarts |

I needed an 18F part that had both 2 Uarts and EEPROM. The 18Fk22 fit this criteria. The 2nd Uart, however, is the same 2 pins, RB6, RB7 that are used for the CCS ICD. How does one go about using this chip and debugging the code? I looked at an 18F25J11 and it has 2 uarts, remappable pins but no EEPROM.
Can I use the 18F25J11 and use program space as "EEPROM" storage for user selectable values?
Thanks. |

yes!
I just did this with a 26J11 project I finished last week.
The reason why a lot of "self programmable" PIC's no longer come with EEPROM is because they can use program flash for application config storage! (at least that's my guess)

For the 18F4XK22 series the 2nd UART is on pins D6/D7.... _________________ Google and Forum Search are some of your best tools!!!! |
