pin.
enabled, the pull-downs are removed until VTR POR.
TEST 7 register (configuration register 0x29), which is used to select logical device numbering in the
LPC47M172. See Table 6.1 - Super I/O Block Logical Device Number and Addresses. The pin has an
internal pull-down resistor that selects the non-SMSC (Intel Compatible) 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.
