Register 0x82100-0x821FF: A1SP RX Change Pointer Table (RX_CHG_PTR)
This table contains the frame pointers, indicating in what frame a channel should
change its active state. The new active state is stored along with the frame
pointer. This table is generated by the RALP when it gets the bit mask updates
in DBCES mode and consumed by the RTFC. When the RFTC gets to the frame
specified in the pointer, if the pending bit is set in the pending table, the RFTC
updates the active table and plays out the appropriate data depending upon the
state of the channel. The structure of the table is shown below.
This table is for chip use only and should not be modified after initialization.
Initialize to all “0”s.
LINE = OFFSET (MOD 256) / 32
