18F252 config
i need change my config because 18F2520 finish in my city....then i but 18F252 and
i have problem with config
code/pic work with 8 mhz internal oscilator with pll = 32mhz
Code work 100%
Code:
asm
__CONFIG _CONFIG1H, _OSC_INTIO7_1H & _IESO_OFF_1H
__CONFIG _CONFIG2H, _WDT_OFF_2H & _WDTPS_512_2H

__CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L
__CONFIG _CONFIG5L, _CP0_ON_5L & _CP1_ON_5L & _CP2_ON_5L & _CP3_ON_5L
__CONFIG _CONFIG5H, _CPB_ON_5H

All possible/relevant CONFIG fuses options are listed at the end of the MPASM .INC files for your particular PIC. Those should help you figure out which ones you need and which ones are incorrect (whether it be spelling, options that are/aren't present, etc).
And exactly what is your question? Having trouble decoding the English...
What isn't working right? What error messages?

The real problem is i need that my 18f252 work with internal oscilator and 32mhz,
in pic18d2520 i use config above and work 100%
asm
__CONFIG _CONFIG1H, _OSC_INTIO7_1H & _IESO_OFF_1H
...
and
DEFINE OSC 32
OSCCON = %11110000 ' 8 Mhz, internal osc
OSCTUNE = %11000000 ' 4x PLL enabled
i need help for corret config in 18F252

This is cut & paste directly from the 18F252 data sheet:
2.1 Oscillator Types
The PIC18FXX2 can be operated in eight different Oscillator modes. The user can program
three configuration bits (FOSC2, FOSC1, and FOSC0) to select one of these eight modes:
1. LP Low Power Crystal
2. XT Crystal/Resonator
3. HS High Speed Crystal/Resonator
4. HS + PLL High Speed Crystal/Resonator with PLL enabled
5. RC External Resistor/Capacitor
6. RCIO External Resistor/Capacitor with I/O pin enabled
7. EC External Clock
8. ECIO External Clock with I/O pin enabled
Note there is no internal oscillator option for the 252. Oops...;o}

thaks all for help.......realy 452 not have internal oscilator.......vendor sad 252 = 2520
arggggggggg.....i'm a donkey....i not read pdf
