I'm setting up hardware SPI as master on PIC MCU please refer to datasheet link at the bottom

Page 359 says we can configure SPI1CON1 register bits SSPM<3:0> for some choices, where I choose value 0010 that is for SPI acting as Master with clock Fosc/64, I'm using MCU internal OSC at 4Mhz that means 4,000,000/64 = 62,500 should I expect 62,500 cycles/sec (SPI clock signals) at SCK pin?

My 2nd question is what max voltage I can expect on SCK while I'm running MCU at 3.3v, I was not able to find any reference to this on datasheet.

Datasheet 16LF18324

That appears to be correct.

My 2nd question is what max voltage I can expect on SCK while I'm running MCU at 3.3v, I was not able to find any reference to this on datasheet.

If not otherwise spec'd, assume normal i/o pin spec. ie minimum of VDD-0.7v @ 6mA

 

Can you please advise what section of datasheet can hold information related to pin logic levels?

Section 35, and for general I/O ports, this table:

 

I'm looking to learn one more think based on above question, as we calculated speed 62,500/sec. is it possible that we can estimate clock (signal) time high, and clock time low from the SPI speed?

I don't think so. I suspect its a square wave.

Hi S,
3.3V if it's 'L'
I would invest in a logic analyser, it will explain a lot, and be very useful.
