5   Implement inter-processor mailbox (IPM) on NXP LPC family.

7Overview
8********
9
10Some NXP microcontrollers from LPC family are dual-core, this
11sample application uses a mailbox to send messages from one
12processor core to the other.
13
14This sample applies to the following boards:
15 -  :zephyr:board:`lpcxpresso54114`, two core processors (Cortex-M4F and Cortex-M0+)
16 -  :zephyr:board:`lpcxpresso55s69`, two core processors (dual Cortex-M33)

48- Speed: 115200
49- Data: 8 bits
50- Parity: None
51- Stop bits: 1
