• Manufacturer Part Number: LPC47M172_07
• Description: Advanced I/O Controller with Motherboard GLUE Logic
• Manufacturer: SMSC [SMSC Corporation]

Note:
(nAUD_LNK_RST)x( nCDC_DWN_ENAB )=nCDC_DWN_RST
SMSC LPC47M172
If GP24 is programmed as GPIO output the GP data bit will also control nCDC_DWN_ENAB input to the
CNR logic.
This follows the boolean equation:
See Table 13.6 for CNR timing.
