FNC 77 – PR / Print (ASCII Code)
Outline
This instruction outputs ASCII code data to outputs (Y) in parallel.
1. Instruction format
2. Set data
3. Applicable devices
Explanation of function and operation
1. 16-bit operation (PR)
ASCII codes stored in low-order 8 bits (1 byte) of
to
+7 are output to
to
+7 in turn by
one character at a time in the time division method.
The timing chart below shows a case in which the following ASCII codes are stored in
to
+7.
Eight bytes are sent from
= "A" at first to "
+7 = "H" at the end.
