P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.

For all SPI slave modes, CLKG is programmed as 1/2 of the CPU clock by setting CLKSM = CLKGDV = 1.

P = 1/CPU clock frequency in ns. For example, when running parts at 250 MHz, use P = 4 ns.

For 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 = 2P if CLKSM = 1 (P = 1/CPU clock frequency)

=Sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)

T =

CLKX period = (1 + CLKGDV) * S

H =

CLKX high pulse width

= (CLKGDV/2 + 1) * S if CLKGDV is even

 

 

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

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).
