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 of
to
+3 are output to
to
+7 in turn by one character at a time in the
time division method.
Eight bytes are sent from the low-order 8 bits (1 byte) of
first to the high-order 8 bits (1 byte) of
+3 at the end.
When data is stored from
to
+3 as shown in the table below, data is sent in the order of A to H of "2.
Timing chart".
2. Timing chart
Types of output signals
•
to
+7: Sending output (
handles low-order bits, and
+7 handles high-order bits.)
•
+8:
Strobe signal
•
+9:
Execution flag which operates as shown in the above timing chart
