• Manufacturer Part Number: LPC47M107S-MS
• Manufacturer: Standard Microsystems (SMSC)

Specifications of LPC47M107S-MS

• Pin Count: 100
• Lead Free Status / RoHS Status: Compliant

Note 1: This register is read-only when GP43 register bit [3:2] = 01 and the GP43 pin is high.
Note 2: Bits [3:2] of this register are reset (cleared) on VCC POR and Hard Reset (and VTR POR).
Note 3: Bit 3 of this register is reset (cleared) on VCC POR and Hard Reset (and VTR POR).
Note 4: The parallel port interrupt defaults to 1 when the parallel port activate bit is cleared.
Note 5: Bits 2 and 3 of the PME_STS4 and SMI_STS4 registers, and bit 3 of the PME_STS5 register may be set on a
REGISTER
VCC POR. If GP32, GP33 and GP53 are configured as input, then their corresponding PME and SMI status
bits will be set on a VCC POR since these pins revert to their non-inverting GPIO output function when VCC
is removed from the part. These GPIOs cannot be used for PME wakeup when the part is under VTR power
(VCC=0).
