• Manufacturer Part Number: LPC47M182
• Description: ADVANCED I/O CONTROLLER WITH MOTHERBOARD GLUE LOGIC
• Manufacturer: SMSC Corporation

Note 1: These bits are R/W bit, but have no effect on circuit operation.
Note 2: These bits when read indicate the current bit status. These bits are set to “0” by writing “0” to individual bit
locations in this register. Producing an interrupt in the SER_IRQ stream by setting these bits to “0” overrides other
interrupt sources for the SER_IRQ stream. No other functional logic in the LPC47M182 sets bits in the register.
These bits are only cleared by writing “1” to the bit location.
