Preliminary
A simplified block diagram of the On-Chip Reset Circuit
is shown in
23.1
Device Reset events are tracked through the RCON
register
ister indicate that a specific Reset event has occurred.
In most cases, these bits can only be cleared by the
event and must be set by the application after the
event. The state of these flag bits, taken together, can
be read to indicate the type of Reset that just occurred.
This is described in more detail in
State of
The RCON register also has control bits for setting
interrupt priority (IPEN) and software control of the
BOR (SBOREN). Interrupt priority is discussed in
