transmit mode.
In GP 1, 2, or 3 FS modes, the
contains the period required for EPPI_FS1 based on the EPPI_CLK clock.
In GP transmit mode with the EPPI_CTL.BLANKGEN bit set, this register contains the number of samples of
active video or vertical blanking samples per line. When used for blanking generation, only the lower 16 bits are
valid.
Note that a value of 0 for this register is illegal. If programmed as 0, the EPPI regards the
register as containing 1.

Frame Sync Period or Samples Number.
In GP 1, 2, or 3 FS modes, the EPPI_FS1_PASPL.VALUE bit field is used for the
generation of frame sync 1 and contains the period required for EPPI_FS1 based on
the EPPI_CLK clock. In GP transmit mode with the EPPI_CTL.BLANKGEN bit
set, this bit field contains the number of samples of active video or vertical blanking
samples per line.
