mmc1_dat[n:0](5) transition

(1) Related with the output clock maximum and minimum frequencies programmable in MMC module.

(2) PO = output clock period in ns

(3) The jitter probability density can be approximated by a Gaussian function.

(4) Corresponding figures showing timing parameters are common with the Standard MMC mode figures.

(5) In MMC1_dat[n:0], n is equal to 3.

(6) The X parameter is defined as follows:

CLKD

1 or Even

0.5

Odd

(trunk[CLKD/2]+1)/CLKD

All required details about clock division factor CLKD can be found in the AM/DM37x Multimedia Device Technical Reference Manual

(literature number SPRUGN4).

(7) The Y parameter is defined as follows:

CLKD

1 or Even

0.5

Odd

(trunk[CLKD/2])/CLKD

All required details about clock division factor CLKD can be found in the AM/DM37x Multimedia Device Technical Reference Manual

(literature number SPRUGN4).

(8) See Section 4.3.4, Processor Clocks.
