would you please help about McBSP

1-As I know in SPI mode there is not the feature to program FPER in
McBSP. I want to read 16-bit samples every 125us in SPI mode. (it is
compulsory). I want to use DMA and not add any checking or time
consuming code to my project.
2- If my cpu internal clk is 120 MHz and the CLKGDV field of my SRGR is
8 bits, how can I use mcbsp(in SPI mode) with internal clk source and
with 100KHz clk(r/x) frequency? It seems that the minimum achievable
clk frequency is (120/(2*255))#5KHz.
