6.1 CONFIGURATION AND FUNCTION
shown in Figure 6-1.
beforehand, simultaneously with the generation of an interrupt from timer/counter 1 or external interrupt, and its output off-chip.
The pins that output the data off-chip are called real-time output ports.
with programmable timing are implemented without software intermediation.
The real-time output function is implemented by hardware, including primarily port 0 and the port 0 buffer registers (P0H, P0L),
The real-time output function refers to the transfer to the output latch by hardware of data prepared in the P0H and P0L
The following two kinds of real-time output data are handled:
• 4 bits
• 8 bits
By combining the real-time output function with the macro service function described later, the functions of a pattern generator
This is ideally suited to stepping motor control, for example.
Figure 6-1 shows the block diagram of the real-time output port.
