The dsPIC30F differentiates between various kinds of
Reset:
• Power-on Reset (POR)
• MCLR Reset during normal operation
• MCLR Reset during Sleep
• Watchdog Timer (WDT) Reset (during normal
• Programmable Brown-out Reset (BOR)
• RESET Instruction
• Reset caused by trap lockup (TRAPR)
• Reset caused by illegal opcode, or by using an
Different registers are affected in different ways by
various Reset conditions. Most registers are not
affected by a WDT wake-up, since this is viewed as the
resumption of normal operation. Status bits from the
RCON register are set or cleared differently in different
Reset situations, as indicated in
are used in software to determine the nature of the
Reset.
A block diagram of the on-chip Reset circuit is shown in

path. The filter detects and ignores small pulses.

The POR circuit inserts a small delay, T
