11 The LPC controller is represented as a multi-function device to account for the
16 * An LPC Host Controller: Manages LPC functions such as host vs slave mode, the
17 physical properties of some LPC pins, configuration of serial IRQs, and
18 APB-to-LPC bridging amonst other functions.
20 * An LPC Host Interface Controller: Manages functions exposed to the host such
21 as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
28 Additionally the state of the LPC controller influences the pinmux
