3.1.5 Signal Edge Definitions
Software must update the FGPO_BASEn register value (where n is the number of the
buffer that interrupted with a buffer done interrupt) BEFORE clearing the buffer done
interrupt flag. This must be done even if the base address of the buffer does not
change.
The DDR Memory controller used in the PNX17xx Series is optimized for 128-byte
block transfers on 128-byte address boundaries. To keep Main Memory bus traffic at
a minimum the programmer should program the FGPO_BASE1 and FGPO_BASE2
with bits [6:0] = 0000000 and program the FGPO_STRIDE to multiples of 128.
During the next-to-last BUFnDONE interrupt service routine turn off (set to ‘0’) the
associated FGPO_CTL.OUTPUT_ENABLE_n bit.
During the last BUFnDONE interrupt service routine turn off (set to ‘0’) the associated
FGPO_CTL.OUTPUT_ENABLE_n bit, the FGPO is now IDLE
The FGPO uses only the rising edge of clk_fgpo. If the negative edge of an external
clock needs to be used, program the PNX17xx Series clock module to invert the
external clock for the FGPO.
