FNC 63 – INCD / Incremental Drum Sequencer
Outline
This instruction creates many output patterns using a pair of counters.
1. Instruction format
2. Set data
3. Applicable devices
S
: "D
.b" cannot be indexed with index registers (V and Z).
Explanation of function and operation
1. 16-bit operation (INCD)
The current value
of a counter is compared with the table data having "n" lines starting from
(which occupies "n" lines x 1 device). When
is equivalent to the table data, the current output is reset,
and the next output is set to ON. In this way, the ON/OFF status of specified outputs is controlled in turn.
