Sequencer RAM

Sequencer RAM Address Map

Address	Byte Field (D16 access only)
8000	First byte of Source data
8001	First byte of Sink data
...	...
FFFE	Last byte of Source data
FFFF	Last byte of Sink data

Notes:
1. The source and sink memories are each 16K bytes long, interleaved with the source being the least significant byte of each 16-bit word, giving 32K bytes (16K words) of sequencer memory in total. 2. The memories have no reset and have undefined values after a power-up cycle; to be safe they should be filled with zeros after each TIM RESET.
