8.3 Microprocessor read/write ISP1161’s internal control registers by
PIO mode
8.3.1
I/O port addressing
Table 3
shows ISP1161’s I/O port addressing. Complete decoding of the I/O port
address should include the chip select signal CS and the address lines A1 and A0.
However, the direction of the access of the I/O ports is controlled by the RD and WR
signals. When RD is LOW, the microprocessor reads data from ISP1161’s data port.
When WR is LOW, the microprocessor writes a command to the command port, or
writes data to the data port.
Figure 11
and
Figure 12
illustrate how an external microprocessor accesses
ISP1161’s internal control registers.
