You could try putting the code you want to be called the fastest, closest to zero vector.
Labels called with a Goto command causes the program counter to start looking for your label from zero,
so the closest it is to zero, the faster it is found, and run.
So without looking at anything else about your code:
Code:
// the following is not run time code, so who cares…
@ device pic16F819, wdt_off, hs_osc, pwrt_on, mclr_off, lvp_off, protect_on
DEFINE OSC 16 ' We're running at 16 Mhz
led var PORTB.1
i var byte
// jump to config vector
Goto Config
Main:
high led
CCP1CON = %00001100 ' Normal PWM mode
T2CON.2 = 1 ' Timebase ON
PAUSE 15
low led
T2CON.2 = 0 ' Timebase OFF
CCP1CON = %00000000 ' Disable PWM to regain control of PortA.2
PAUSE 5
Goto Main
Config:
ADCON1=%01001110 ' Digital only for all pins
CCP1CON = %00001100 ' Normal PWM
PR2 = 3
CCPR1L =0
CCP1CON.5 = 1
CCP1CON.4 =1
For i = 0 to 9
Toggle LED
Pause 500
NEXT
// run main program
Goto Main
