³For all SPI slave modes, CLKG is programmed as 1/2 of the CPU clock by setting CLKSM = CLKGDV = 1. § S = sample rate generator input clock = P if CLKSM = 1 (P = 1/CPU clock frequency)

L =

CLKX low pulse width

= (CLKGDV/2) * S if CLKGDV is even

=(CLKGDV + 1)/2 * S if CLKGDV is odd or zero

FSRP = FSXP = 1. As a SPI master, FSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on FSX and FSR is inverted before being used internally.

CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP

#FSX should be low before the rising edge of clock to enable slave devices and then begin a SPI transfer at the rising edge of the master clock (CLKX).
