Reset
The
dsPIC30F3014/4013
differentiates
between
various kinds of Reset:
a)
Power-on Reset (POR)
b)
MCLR Reset during normal operation
c)
MCLR Reset during Sleep
d)
Watchdog Timer (WDT) Reset (during normal
operation)
e)
Programmable Brown-out Reset (BOR)
f)
RESET
Instruction
g)
Reset caused by trap lockup (TRAPR)
h)
Reset caused by illegal opcode or by using an
uninitialized W register as an Address Pointer
(IOPUWR)
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 Table 20-5. These bits are
used in software to determine the nature of the Reset.
A block diagram of the On-Chip Reset Circuit is shown
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.

POR: POWER-ON RESET
A power-on event generates an internal POR pulse
when a VDD rise is detected. The Reset pulse occurs at
the POR circuit threshold voltage (VPOR) which is nom-
inally 1.85V. The device supply voltage characteristics
must meet specified starting voltage and rise rate
requirements. The POR pulse resets a POR timer and
places the device in the Reset state. The POR also
selects the device clock source identified by the
oscillator configuration fuses.
The POR circuit inserts a small delay, TPOR, which is
nominally 10
s and ensures that the device bias
circuits are stable. Furthermore, a user-selected
power-up time-out (TPWRT) is applied. The TPWRT
parameter is based on device Configuration bits and
can be 0 ms (no delay), 4 ms, 16 ms, or 64 ms. The
total delay is at device power-up, TPOR + TPWRT. When
these delays have expired, SYSRST is negated on the
next leading edge of the Q1 clock and the PC jumps to
the Reset vector.
