Should you notice a conflict between my narration and the official Microchip documentation, ALWAYS refer to the latter. However please send me an email if a conflict arises.

Errata

• Page 18, the final text paragraph, just above the code listing, refers to the "AD1PCGF " SFR. This should be "AD1PCFG" .

• Page 202, the statement:
  #define U_TX 0x0400 // enable tx, clear all flags
  
  Should be changed to:
  #define U_TX 0x1400 // enable tx & rx, clear all flags
  
  So that both RX and TX are enabled, which is necessary for the following demo to work.
