8.5 RCON Register

The RCON register contains flag bits which are used to

determine the cause of the last Reset or wake-up from

Idle or Sleep modes. RCON also contains the IPEN bit

which enables interrupt priorities.

The operation of the SBOREN bit and the Reset flag

bits is discussed in more detail in Section 4.1 “RCON

Register”.
