through the L64007. This can result in transport data
backing up in the buffers.
After reset, this bit is 0, selecting the AUX mode.
The following table delineates the operations for the pos-
sible settings of the AUX_002 and AV_S/P ports.
AV_S/P
Audio/Video Interface in Serial or Parallel
3
This bit determines if the A/V decoder interface operates
in serial (when bit is set to 0) or 8-bit parallel mode (when
bit is set to 1). Internally it determines if the data out from
the on-chip transport buffers is directed to the AVSD pin
in serial mode, or to the AUXD[7:0] pins in parallel mode.
After reset, the bit is 0 (serial mode). Also see the truth
table for AUX_002, above.
CH_S/P
Channel Decoder Serial or Parallel
2
This bit determines if the channel decoder interface oper-
ates in serial (when set to 0) or 8-bit parallel mode (when
set to 1). After reset, the bit is 0 (serial mode).
FSC_SEL
Frequency Synthesizer Value Select
1
This bit multiplexes the data written to the FSC clock
divide register. When set to 1, this bit selects the DCO
clock divide value, DCO_DIV. When 0, it selects the ref-
erence clock divide value, REF_DIV. This bit toggles after
each write of the FSC Clock Divide Value Register. After
reset, this bit is 0.
RST
Software Reset
0
When set to1, this bit generates an internal reset pulse
similar in effect to the hardware reset pulse generated by
the input reset pin. As a result of software reset, all inter-
nal state machines enter the idle state. However, no val-
ues stored in various register les are affected by the
AUX_002
