This Configuration bit, when unprogrammed (left in the
‘1’ state), enables the external MCLR function. When
programmed, the MCLR function is tied to the internal

The PIC12F510/16F506 devices incorporate an on-
chip Power-on Reset (POR) circuitry, which provides
an internal chip Reset for most power-up situations.
The on-chip POR circuit holds the chip in Reset until
V
ation. The POR is active regardless of the state of the
MCLR enable bit. An internal weak pull-up resistor is
implemented using a transistor (refer to Table 13-3 for
the pull-up resistor ranges). This will eliminate external
RC components usually needed to create an external
Power-on Reset. A maximum rise time for V
ified. See Section 13.0 “Electrical Characteristics”
for details.
When the devices start normal operation (exit the
Reset condition), device operating parameters (volt-
age, frequency, temperature,...) must be met to ensure
operation. If these conditions are not met, the devices
must be held in Reset until the operating parameters
are met.

A simplified block diagram of the on-chip Power-on
Reset circuit is shown in Figure 10-7.
The Power-on Reset circuit and the Device Reset
Timer (see Section 10.5 “Device Reset Timer
(DRT)”) circuit are closely related. On power-up, the
Reset latch is set and the DRT is reset. The DRT timer
begins counting once it detects MCLR, internal or
external, to be high. After the time-out period, it will
reset the Reset latch and thus end the on-chip Reset
signal.
A power-up example where MCLR is held low is shown
in Figure 10-8. V

The time between when the DRT senses that MCLR is

situations, we recommend that external RC circuits be
used to achieve longer POR delay times (Figure 10-9).
