Abstract
Microcontroller programming requires efficient techniques for register access. Registers are used to configure the CPU and peripheral hardware devices such as flash access, clocks, I/O ports, timers, communication interfaces (UART, SPITM, CAN [1]), etc. This chapter describes C++ methods that can be used to manipulate microcontroller registers. The focus of this chapter is placed on template methods that provide for efficient, scalable and nearly portable register access.

Notes
- 1.
Note, however, that a register’s width need not necessarily have the same type as its address. One often encounters registers with 8–bit width or 16–bit width on a 32–bit machine, etc.
- 2.
This example and the following one have been taken from code that I once wrote to initialize timer0 for a well-known 32–bit microcontroller.
