ISP1161A internal control registers.

Register access phases
The ISP1161A register structure is a command-data register pair structure. A
complete register access cycle comprises a command phase followed by a data
phase. The command (also known as the index of a register) points the ISP1161A to
the next register to be accessed. A command is 8 bits long. On a microprocessor’s
16-bit data bus, a command occupies the lower byte, with the upper byte filled with
zeros.
Figure 12
shows a complete 16-bit register access cycle for the ISP1161A. The
microprocessor writes a command code to the command port, and then reads or
writes the data word from or to the data port. Take the example of a microprocessor
attempting to read the ISP1161A’s ID. The ID is kept in the HC’s HcChipID register
(index 27H, read only). The 16-bit register access cycle is therefore:
1. Microprocessor writes the command code of 27H (0027H in 16-bit width) to the
HC command port
2. Microprocessor reads the data word of the chip’s ID from the HC data port.
When A1 = 0, the microprocessor accesses the HC.
When A1 = 1, the microprocessor accesses the DC.
Fig 10. A microprocessor accessing an HC or a DC via an automux switch.
When A0 = 0, the microprocessor accesses the data port.
When A0 = 1, the microprocessor accesses the command port.
