with the ability to change an unused OSC2 pin into an additional input/output (I/O) pin. A PLL clock that is four times the multiplier circuit is available, and it allows the PIC18 microcontroller to run with a one instruction cycle per clock cycle. Rounding out the features, the PIC18 can be driven by a TMR1 oscillator for reduced power or faster application execution. This may seem like a dizzying array of options, but they can be listed as

LP and XT modes execute exactly the same way on the PIC18 as on the other PIC microcontrollers. RC can work exactly the same with a one-quarter-speed clock driven out of the OS2 pin or can have the OSC2 pin changed to the RA6 I/O pin; this is known as RCIO mode. The external oscillator option will take in an external clock signal and output a one-quarter-speed clock on OSC2 unless the OSC2 pin is to be used as RA6 (like the RC oscillator mode and known as ECIO mode). The external oscillator will work for all data speeds from dc to 48 MHz that the PIC18 can run at. The RC, RCIO, XT, LP, ES, ESIO, HS, and HSPLL oscillator modes are selected at programming time within the PIC18 s con guration fuses. One of the most interesting features of the PIC18 is HS mode, which can run like a typical PIC microcontroller, from 4 to 40 MHz and in some part numbers 48 MHz. An optional phased-locked-loop (PLL) clock multiplier can be added to the external clock (with the external clock limited to 10 MHz). This feature (known as HSPLL mode) allows a 10-MHz PIC18 microcontroller to run as if it were being driven with a 40-MHz clock.
BASIC OPERATING FEATURES
The advantages of this feature include reduced EMI emissions from the PIC microcontroller and reduced oscillator power consumption. The last oscillator mode consists of software enabling the TMR1 oscillator as the PIC18 microcontroller s processor clock source. This feature allows application execution with I/O polling and interrupts to continue, except at a vastly reduced rates (and power consumption). This mode is enabled and disabled by setting and resetting, respectively, the SCS bit of the PIC18 s OSCON register. For this mode to work, the OSCON bit of the con guration fuses must be reset. When the TMR1 oscillator is enabled (by setting the SCS bit), execution moves over immediately to the TMR1 clock, and the standard oscillator is shut down. This transition is very fast, with only eight TMR1 clock cycles lost before execution resumes with TMR1 as the clock source. When transitioning from TMR1 to the standard oscillator, the oscillator is restarted with a 1024cycle delay for the clock to stabilize before resuming execution. The oscillator circuit in the PIC18Cxx appears in block diagram form in Fig. 9.13.
RESET
Reset in the PIC microcontroller is very simple and easy to implement, as shown in Fig. 9.14, and with many recently released PIC microcontroller part numbers, the task of implementing reset has been simpli ed even more with the addition of internal reset capabilities and optional built-in brown-out reset (BOR) or brown-out detect (BOD) functions in some of the new parts. These functions, along with a 72-ms powerup delay function (the PWRTE bit of the con guration register), make it easy to come up with an application with good reset characteristics in a variety of situations with little or no external hardware. The simple pull-up on MCLR# (the master clear pin) is really all that is required for most applications where an external reset is required. This may be a departure for you,
