3.3 MUXOUT Interface
The MUXOUT bus lets you probe any point in the device while receiving
a transport stream (TS).
Important:
MUXOUTBUS is 27 bits wide. For each probed point, data and control
signals are available on this bus (including the clock). The clock has the
same aspect ratio as CLKMUXIN; it is not a 50% duty cycle type.
Software controls the MUXOUTBUS, which provides five test
possibilities. The control word is MUXOUT_select[2:0], located at
address 0x15 (bits 2 to 0).
Table 3.3
Note that the MUXOUT bus can be 3-stated by asserting the
MUX_CTRL bit (bit 3 of the Mode Register Address Line), at address
0x19. The bus is active when MUX_CTRL is set to 0.
