The closest I've come across is hardware manchester capability in the
AT90PWM2/2B/3/3B:

· USART Extended mode (EUSART) with:
   ­ Independant bit number configuration for transmit and receive
   ­ Supports Serial Frames with 5, 6, 7, 8, 9 or 13, 14, 15, 16, 17 Data Bits 
and 1 or 2 Stop Bits
   ­ Biphase Manchester encode/decoder (for DALI Communications)
   ­ Manchester framing error detection
   ­ Bit ordering configuration (MSB or LSB first)
   ­ Sleep mode exit under reception of EUSART frame

However, it couldn't take too long to port the implementation in
P16/ManReceive6.mil at http://www.mikroe.com/en/projects/mikrobasic.php,
especially using the overview in P16/ManReceive6.pbas. (But I grant it's
easier still, if it's already been done. :-)
