20.3
The dsPIC30F5011/5013 devices differentiate 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 var-
ious Reset conditions. Most registers are not affected
by a WDT wake-up since this is viewed as the resump-
tion of normal operation. Status bits from the RCON
register are set or cleared differently in different Reset
situations, as indicated in
used in software to determine the nature of the Reset.
A block diagram of the On-Chip Reset Circuit is shown
in
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.

nominally 1.85V. The device supply voltage character-
istics must meet specified starting voltage and rise rate
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 oscil-
lator configuration fuses.
The POR circuit inserts a small delay, T
nominally 10 μs and ensures that the device bias cir-
cuits are stable. Furthermore, a user selected power-
up time-out (T
