S12XE Periodic Interrupt Timer

rayhall — Thu, 24 Sep 2015 09:01:01 GMT

I have been looking at the datasheet for the S12XEP100 and I find there is two Periodic Interrupt Timers listed. These are,

S12PIT24B4CV2 (Four Timers)

S12PIT24B8CV2 (Eight Timers)

Does this mean the are a total of twelve PIT timers ?.
If so I cannot find the output pins for the extra four.

If some S12XE only have four PIT timers, then I cannot find this information in the datasheet.

Ray.

Hi Ray,

No, maximum is 8 channels.

Please look at Appendix D Derivative Differences in reference manual.

9S12XEP100, 9S12XEP768 have 8 channels PIT module.

Derivatives with lower amount of Flash has just four channel PIT module.

I hope it helps you.

Have a great day,
RadekS
