DATASHEET
Chapter 6 Functional Description
The following sections describe the functional blocks located in the LPC47M182 (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 167).
6.1
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, 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 base addresses of the blocks can be programmed via the configuration
registers. Refer to the “Configuration” section for configuration register description.
