Field GFLADJ_REFCLK_240MHZ_DECR
reader - GFLADJ_REFCLK_240MHZ_DECR
This field indicates the decrement value that the controller applies
for each ref_clk in order to derive a frame timer in terms of a
240-MHz clock.
This field must be programmed to a non-zero value only if
GFLADJ_REFCLK_LPM_SEL is set to 1.
The value is derived as follows:
GFLADJ_REFCLK_240MHZ_DECR = 240/ref_clk_frequency
Examples: If the ref_clk is 24 MHz then
-
GUCTL.REF_CLK_PERIOD = 41
-
GFLADJ.GFLADJ_REFCLK_240MHZ_DECR = 240/24 = 10
