Note:
SMSC/Non-SMSC Register Sets (Rev. 01-11-07)
The pin has an internal pull-down resistor that selects the non-standard SMSC (Intel Compatible) mode. To
select this mode, the pin should be left unconnected. This configuration clears the LD_NUM bit to ‘0’ and the
associated functionality corresponds to the existing functionality in the part when the LD_NUM bit=0.
Connecting this pin to VTR will select the standard SMSC mode of the logical device numbering. This
configuration sets the LD_NUM bit to ‘1’ and the associated functionality corresponds to the existing functionality
in the part when the LD_NUM bit=1.
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
LPC47M172. See Table 6.1 - Super I/O Block Logical Device Number and Addresses. The pin functions
as follows:
