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
Figure
A MCLR noise filter is provided in the MCLR Reset
path. The filter detects and ignores small pulses.
Internally generated Resets do not drive MCLR pin low.

requirements. The POR pulse will reset a POR timer
and place the device in the Reset state. The POR also
selects the device clock source identified by the

The POR circuit inserts a small delay, T
