Notes:
1) HARD RESET: nPCI_RESET pin asserted
2) SOFT RESET: Bit 0 of Configuration Control register set to one
3) All host accesses are blocked for 500µs after Vcc POR (see Power-up Timing Diagram)
LD_NUM Bit
The LD_NUM bit in the TEST 7 global configuration register (0x29) is used to select between the logical device
numbering in the LPC47M182. See the TEST 7 register for LD_NUM bit description. Table 11.1 and Table 11.2
summarize the logical device registers when LD_NUM bit is 0 and 1.
