5.12.3.1.2 Exiting The High Speed Halt Mode
There is a choice of methods for exiting the HALT mode: a chip Reset using the RESET pin or a Multi-
Input Wake-up.
5.12.3.1.3 HALT Exit Using Reset
A device Reset, which is invoked by a low-level signal on the RESET input pin, takes the device out of the
HALT mode and starts execution from address 0000H. The initialization software should determine what
special action is needed, if any, upon start-up of the device from HALT. The initialization of all registers
following a RESET exit from HALT is described in the Reset section of this manual.
5.12.3.1.4 HALT Exit Using Multi-Input Wake-up
The device can be brought out of the HALT mode by a transition received on one of the available Wake-
up pins. The pins used and the types of transitions sensed on the Multi-input pins are software
programmable. For information on programming and using the Multi-Input Wake-up feature, refer to the
A start-up delay is required between the device wake-up and the execution of program instructions,
depending on the type of chip clock. The start-up delay is mandatory, and is implemented whether or not
the CLKDLY bit is set. This is because all crystal oscillators and resonators require some time to reach a
stable frequency and full operating amplitude.
The IDLE Timer (Timer T0) provides a fixed delay from the time the clock is enabled to the time the
program execution begins. Upon exit from the HALT mode, the IDLE Timer is enabled with a starting
value of 256 and is decremented with each instruction cycle. (The instruction clock runs at one-fifth the
frequency of the high speed oscillator.) An internal Schmitt trigger connected to the on-chip CKI inverter
ensures that the IDLE Timer is clocked only when the oscillator has a large enough amplitude. (The
Schmitt trigger is not part of the oscillator closed loop.) When the IDLE Timer underflows, the clock signals
are enabled on the chip, allowing program execution to proceed. Thus, the delay is equal to 256
instruction cycles.
NOTE
To ensure accurate operation upon start-up of the device using Multi-input Wake-up, the
instruction in the application program used for entering the HALT mode should be followed
by two consecutive NOP (no-operation) instructions.
5.12.3.1.5 Options
This device has two options associated with the HALT mode. The first option enables the HALT mode
feature, while the second option disables HALT mode operation. Selecting the disable HALT mode option
will cause the microcontroller to ignore any attempts to HALT the device under software control. Note that
this device can still be placed in the HALT mode by stopping the clock input to the microcontroller, if the
program memory is masked ROM. See the Option section for more details on this option bit.
