In SPI Slave mode with slave select enabled

(SSPM<3:0> = 0100), the minimum time between

the falling edge of the SS pin and first SCK edge

is greater than specified in parameter 70 in

Table 26-14 and Table 26-16. The updated

specification is shown in bold in Table 1.

The minimum time between SS pin low and an

SSPBUF write is also 3 T

the SS pin occurs greater than 3 T

first SCK edge, or loading SSPBUF, the peripheral

will function correctly. Also, if SSPBUF is written

prior to the SS pin going low, the peripheral will

function correctly.
