Product data
Most of the ISP1161A internal control registers are 16 bits wide. Some of the internal
control registers have 32-bit width.
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-bits, followed by the upper 16-bits.
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
