• Manufacturer Part Number: FDC37N769_07
• Description: 3.3V Super I/O Controller with Infrared Support for Portable Applications
• Manufacturer: SMSC [SMSC Corporation]

CR11
CR11 can only be accessed in the configuration state and after the CSR has been initialized to 11H. The default
value of this register after power up is 80H (Table 94). CR11 is a test control register and all bits must be treated as
Reserved. NOTE: all test modes are reserved for SMSC use. Activating test mode registers may produce undesired
results.
CR12 - CR13
CR12 - CR13 are reserved. Reserved registers cannot be written and return “0” when read. The default value of
these registers after power up is 00H.
CR14
CR14 can only be accessed in the configuration state and after the CSR has been initialized to 14H. CR14 shadows
the bits in the write-only FDC run-time DSR register (Table 95).
CR15
CR15 can only be accessed in the configuration state and after the CSR has been initialized to 15H. CR15 shadows
the bits in the write-only UART1 run-time FCR register (Table 96).
