5.0
PIC16C5X devices may be RESET in one of the follow-
ing ways:
• Power-On Reset (POR)
• MCLR Reset (normal operation)
• MCLR Wake-up Reset (from SLEEP)
• WDT Reset (normal operation)
• WDT Wake-up Reset (from SLEEP)
Table 5-1 shows these RESET conditions for the PCL
and STATUS registers.
Some registers are not affected in any RESET condi-
tion. 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 (POR), MCLR or
WDT Reset. A MCLR or WDT wake-up from SLEEP
also results in a device RESET, and not a continuation
of operation before SLEEP.

The TO and PD bits (STATUS <4:3>) are set or cleared
depending on the different RESET conditions (Table 5-
1). These bits may be used to determine the nature of
the RESET.
Table 5-3 lists a full description of RESET states of all
registers. Figure 5-1 shows a simplified block diagram
of the On-chip Reset circuit.
