Re: K42 and Timer Interrupts

Thanks for the explanation.

I misinterpreted these paragraphs. My understanding was to have ASYNC cleared and use Fosc/4.

Re: K42 and Timer Interrupts

The SYNC block uses FOSC/4 as its sync clock, so it's difficult to use it if it's using FOSC/4 as its input source for counting too.

for 16-bit read/write see sec 20.1.1.1:

Re: K42 and Timer Interrupts

Sure it is. Inside the ISR, Timer 0 is stopped, reloaded and restarted.

I think is it obligatory to use Fosc/4. Unless I misunderstood the DS. Then why is it necessary to use ASYNC=1? Could...

Re: K42 and Timer Interrupts

Two things...

Since you're using FOSC/4 as the source, set ASYNC bit in T0CON1.

Also, when using 16 bit mode (MD16=1) you should always write TMR0H then TMR0L in that order so that the high...

Re: K42 and Timer Interrupts

looks like not reloading the tmr count every ms....... after first int, tmr counter looping from 0 .....???

Tried the files and indeed it worked OK. Sort off...

I tried to setup the Timer 0 as 16bit timer, cloked by Fosc/4 with system clock at 64MHz.

K42 and Timer Interrupts

I wonder if anyone managed to work with DT-INTS18 with the K42 series chips.

The latest DT_INTS-18_K42c.bas file that tumbleweed posted (on this closed thread...
