The following sections describe the functional blocks located in the LPC47M172 (see Figure 4.1). The
various Super I/O components are described in the following sections and their registers are implemented
as typical Plug-and-Play components (see section Chapter 11 − Configuration on page 172).
Super I/O Registers
Table 6.1 shows the logical device number and addresses of FDC, Serial and Parallel ports,
Keyboard/Mouse, Power Control and GPIO Block, Runtime register block and configuration register block
of the Super I/O immediately after power up. The logical device numbering is controlled by the LD_NUM
bit in the TEST 7 configuration register (0x29). The state of LD_NUM is determined by pin 117 as
described in Chapter 2. The base addresses of the blocks can be programmed via the configuration
registers. Some addresses are used to access more than one register. Refer to the “Configuration”
section for configuration register description.
