'[PICLIST] [PIC] 12C508A T0CKI Schmitt trigger or n'

Hi,

it is not clear from the data sheet, but is the T0CKI pin on a PIC12C508A
based on a Schmitt trigger?  It would be terribly useful to know, and also
whether the T0CKI pin on other PIC family members has the same property.

Andy

Hi Andy, it's clearly shown on page 11 of the
datasheet, yes it is ST type.

Am I the only person who prints out the major
datasheets and puts them in folders??

Hi Andy,

Yes T0CKI is a Schmitt trigger throughout the pic line. Or perhaps it's a
Smith trigger, as I saw printed in a Revox A-700 service manual? In their
case, probably a Swiss trigger :-)

Every 12C508A you get will have different thresholds, which will vary
depending on how you use other pins on the chip and how much current the
chip is consuming. Thank you Microchip.

Cheerful regards,

Bob

Err, no, you are not the only one that does this, although in the case of
the 12C508A I actually have a nice printed, bound booklet.  Sadly, however,
I am a moron, and whilst I did look all through section 6 which describes
TMR0 and T0CKI in great detail, it omitted to mention whether T0CKI was a
Schmitt trigger.  You are indeed correct, and it is casually mentioned in
Table 3-1 on page 11. (although why they couldn't have shown it in the
diagram of the pin in Figure 6-1 I don't know... mutter mutter)

Thank you,

Andy
