Sample Code for setting the fuse for HS mode (Primary Oscillator)
#fuses HS, PR, NOWDT
#use delay(clock=20000000) // A 20 Mhz crystal is used
Sample Code for setting fuses for FRC Internal Oscillator mode
#fuses FRC, NOWDT
#use delay(clock=7370000) // Internal FRC clock of 7.37 Mhz is used
Sample Code for setting fuses for FRC Internal Oscillator mode with PLL enabled
#fuses FRC_PLL16, PR_PLL, NOWDT
#use delay(clock=117920000) // Internal FRC clock of 7.37 * 16 = 117.92 Mhz is used
Sample Code for setting fuse for HS mode using PLL options. The following PLL options are
applicable for the HS fuse:
HS2_PLLx : Divide by 2, x times PLL enabled.
HS3_PLLx : Divide by 3, x times PLL enabled.
#fuses HS2_PLL8, PR_PLL, NOWDT
#use delay(clock=20000000) // A 20 Mhz crystal is used
The 30F2020 , 30F1010 and 30F2023 chips are quite different from the other 30F chips
One major difference is that the Instruction clock is divide by 2 of the actual input clock. The other
chips in the family use a divide by 4.
Crystal Frequency Limitations for various fuses:
HS Mode 10 – 25 MHz
XT Mode 4 – 10 MHz
EC Mode 4 – 10 Mhz
Note: The upper limits of these crystal setting will change when the PLL fuses are used. (For
example HS2_PLL16, EC_PLL16). At no point should the system clock exceed 120 MHz after the
PLL block. The instruction clock for the 30F chips is derived by dividing this final clock by 4. So, the
maximum clock rate for the 30F chips is 30 MHz.
