Register descriptions
The PNX8510/11 register space is divided into four different spaces. Each of them is
addressed by a different I
2
C device address. The first address space is dedicated to
the primary video channel, the second space belongs to the secondary video
channel. The third I
2
C address space accommodates the registers that control the
first audio channel. The fourth I
2
C space is used to address the secondary audio
channel.
The video channel registers are only listed once. Because the secondary video
channel does not support high definition or RGB output, its registers have some
minor differences, which are noted in
Table 28
and
Table 29
as “Not present in
secondary video channel.”
The slave addresses are selectable during boot. The registers for the primary and
secondary audio and video modules are identical, except as noted in the register
definitions.
Table 28
and
Table 29
provide the offset– the base address is dependent
on the module.
The actual address spaces are determined at boot time according to the GPIO
settings. For more information refer to
Section 7.4
.
