Timer0

[Santiago]

I think there is a bug in timer.h, function: SInitTimer0 (line 152), that affects to the counter mode.

This is the actual fuction:

Sub SInitTimer0

    OPTION_REG = OPTION_REG AND 192

    SET OPTION_REG.PSA OFF

    if TMR0Source = Osc THEN SET OPTION_REG.T0SE OFF

    if TMR0Source = Ext THEN SET OPTION_REG.T0SE ON

    clrwdt

    OPTION_REG = OPTION_REG OR TMR0Pres

End Sub

The error is in: OPTION_REG.T0SE when it should be OPTION_REG.T0SC (source clock)

I also suggest an easy optimization:

Sub Sub SInitTimer0
OPTION_REG = OPTION_REG AND 192
if TMR0Source = Ext THEN SET OPTION_REG.T0SC ON
OPTION_REG = TMR0Pres OR OPTION_REG 
clrwdt
End Sub

All bit refering to timer0 are cleared at: OPTION_REG AND 192
Then the lines that clear a bit are no needed:

    SET OPTION_REG.PSA OFF
    if TMR0Source = Osc THEN SET OPTION_REG.T0SE OFF

And This line generates a shorter asm code than the original:

OPTION_REG = TMR0Pres OR OPTION_REG

Sorry there is a typo error in my previous post:

OPTION_REG.T0SC is erroneus

it should be: OPTION_REG.T0CS
