Most of the ISP1160’s internal control registers are 16-bit wide. Some of the internal
control registers, however, are 32-bit wide.
Figure 7
shows how the ISP1160’s 32-bit
internal control register is accessed. The complete cycle of accessing a 32-bit
register consists of a command phase followed by two data phases. In the two data
phases, the microprocessor first reads or writes the lower 16-bit data, followed by the
upper 16-bit data.
To further describe the complete access cycles of the internal control registers, the
status of some pins of the microprocessor bus interface are shown in
Figure 8
.
8.4 FIFO buffer RAM access by PIO mode
Since the ISP1160’s internal memory is structured as a FIFO buffer RAM, the FIFO
buffer RAM is mapped to dedicated register fields. Therefore, accessing the internal
FIFO buffer RAM is similar to accessing the internal control registers in multiple data
phases.
