TABLE 5-3:
RESET DELAY TIMES FOR VARIOUS DEVICE RESETS
5.2.1
POR AND LONG OSCILLATOR
START-UP TIMES
The oscillator start-up circuitry and its associated delay
timers are not linked to the device Reset delays that
occur at power-up. Some crystal circuits (especially
low-frequency crystals) have a relatively long start-up
time. Therefore, one or more of the following conditions
is possible after SYSRST is released:
The oscillator circuit has not begun to oscillate.
The Oscillator Start-up Timer has not expired (if a
crystal oscillator is used).
The PLL has not achieved a lock (if PLL is used).
The device will not begin to execute code until a valid
clock source has been released to the system. There-
fore, the oscillator and PLL start-up delays must be
considered when the Reset delay time must be known.
5.2.2
FAIL-SAFE CLOCK MONITOR
(FSCM) AND DEVICE RESETS
If the FSCM is enabled, it begins to monitor the system
clock source when SYSRST is released. If a valid clock
source is not available at this time, the device auto-
matically switches to the FRC oscillator and the user
can switch to the desired crystal oscillator in the Trap
Service Routine.
5.2.2.1
FSCM Delay for Crystal and PLL
Clock Sources
When the system clock source is provided by a crystal
oscillator and/or the PLL, a small delay, TFSCM, is auto-
matically inserted after the POR and PWRT delay
times. The FSCM does not begin to monitor the system
clock source until this delay expires. The FSCM delay
time is nominally 100
μs and provides additional time
for the oscillator and/or PLL to stabilize. In most cases,
the FSCM delay prevents an oscillator failure trap at a
device Reset when the PWRT is disabled.
5.3
Special Function Register Reset
States
Most of the Special Function Registers (SFRs) associ-
ated with the CPU and peripherals are reset to a
particular value at a device Reset. The SFRs are
grouped by their peripheral or CPU function and their
Reset values are specified in each section of this manual.
The Reset value for each SFR does not depend on the
type of Reset, with the exception of two registers. The
Reset value for the Reset Control register, RCON,
depends on the type of device Reset. The Reset value
for the Oscillator Control register, OSCCON, depends
on the type of Reset and the programmed values of the
oscillator Configuration bits in the FOSC Configuration
register.

Note 1:
TPOR = Power-on Reset delay (10
μs nominal).
2:
TSTARTUP = Conditional POR delay of 20
μs nominal (if on-chip regulator is enabled) or 64 ms nominal
Power-up Timer delay (if regulator is disabled). TSTARTUP is also applied to all returns from powered-down
states, including waking from Sleep mode, only if the regulator is enabled.
3:
TRST = Internal state Reset time (20
μs nominal).
4:
TOST = Oscillator Start-up Timer. A 10-bit counter counts 1024 oscillator periods before releasing the
oscillator clock to the system.
5:
TLOCK = PLL lock time (20
μs nominal).
6:
TFSCM = Fail-Safe Clock Monitor delay (100
μs nominal).
