AM2431: MCSPI Switching Characteristics

futoshi kawarazaki

Part Number: AM2431

I am looking at the AM2431 datasheet(SPRSP65F).
I have a question about the SM8 in "Table 7-65. MCSPI Switching Characteristics - Controller Mode" on page 193.
It states B = (TCS + .5) * TSPICLKREF.
Wouldn't the correct answer be B = (TCS + .5) * Fratio * TSPICLKREF?

Hello,

It looks like there is a mistake in the formula, it should be:

B = (TCS + 0.5) * Fratio * TSPICLKREF

your assumption is correct.

Best,

Daniel
