This chapter discusses the processes and features involved in controlling the
flow of a program on the ’C2xx.

Program control involves controlling the order in which one or more blocks of
instructions are executed. Normally, the flow of a program is sequential: the
’C2xx executes instructions at consecutive program-memory addresses. At
times, a program must branch to a nonsequential address and then execute
instructions sequentially at that new location. For this purpose, the ’C2xx sup-
ports branches, calls, returns, repeats, and interrupts.

The ’C2xx also provides a power-down mode, which halts internal program
flow and temporarily lowers the power requirements of the ’C2xx.
