Hi,

    I built a circuit interfacing a MAX153 parallel 8 bit ADC and a MAX205
RS232 transceiver to a 16F628. It is supposed to read the parallel ADC
output and serialize the data before sending to the computer.

The PIC in this case is running very very hot, i could barely touch it for a
sec. What could be the cause?

this is the ASM its running.
main:    call init
loop:    movlw D'100'
            call  nmsec
            bsf PORTB,0
            call micro4
            bcf PORTB,0

            movf PORTA,0    ; PORTA reads lower 1/2 the byte
            addwf PORTB,0    ; PORTB 4-7 reads higher 1/2 and combines into
1 byte to W

            movwf  TXREG
            goto  loop
