time the pin will reflect the state of the transmit output of the Serial Port 2 block. This is a VCC powered
pin.
Note 10: These pins are internally pulled down to VSS only until Serial Port 2 is enabled. Once Serial Port 2 is
enabled, the pull-downs are removed until VTR POR.
Note 11: Pin 117 is used to select the mode of the logical device numbering. This pin affects the LD_NUM bit in the
TEST 7 register (configuration register 0x29), which is used to select logical device numbering in the
LPC47M182. The pin has an internal pull-down resistor that selects the non-SMSC mode. To select this
mode, the pin should be left unconnected. Connecting this pin to VTR will select the SMSC mode of the
logical device numbering.
