Name:
Framebuffer Block Fill Lower color
Unit:
FramebufferWrite
Region: 0
Offset:

Tag:

Reset Value:
Undefined
Read/write

32 bit value
Contains the color (and optionally alpha value) to be written to the framebuffer during block
writes. Note the format is the raw data format of the framebuffer. Each block fill writes a
pattern of 8 bytes defined by these registers, repeating the same data until 32 pixels have
been filled.
If the framebuffer is used in 8 bit packed mode, then data should be repeated in all 4 bytes
of the register.
If the framebuffer is in 16 bit packed mode then the data must be repeated in both halves
of the register.
