10.3
The PIC16CE62X differentiates between various kinds
of reset:
a)
b)
c)
d)
e)
f)
Some registers are not affected in any reset condition.
Their status is unknown on POR and unchanged in any
other reset. Most other registers are reset to a “reset

state” on Power-on reset, MCLR reset, WDT reset and
MCLR reset during SLEEP. They are not affected by a
WDT wake-up, since this is viewed as the resumption
of normal operation. TO and PD bits are set or cleared
differently in different reset situations as indicated in
Table 10-4. These bits are used in software to deter-
mine the nature of the reset. See Table 10-6 for a full
description of reset states of all registers.
A simplified block diagram of the on-chip reset circuit is
shown in Figure 10-6.
The MCLR reset path has a noise filter to detect and
ignore small pulses. See Table 13-5 for pulse width
specification.
See Table 10-3 for time-out situations.
