Register access phases
ISP1161’s 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 ISP1161 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 13
shows a complete 16-bit register access cycle for ISP1161. The
microprocessor writes a command code to the command port, and then reads from or
writes the data word to the data port. Take the example of a microprocessor
attempting to read a chip’s ID, which is saved in the HC’s HcChipID register (27H,
read only) where its command code is 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
ISP1161’s HC command port
2. Microprocessor reads the data word of the chip’s ID (6110H) from ISP1161’s HC
data port.
When A1 = 0, microprocessor accesses the HC.
When A1 = 1, microprocessor accesses the DC.
Fig 11. A microprocessor accessing a HC or a DC via an automux switch.
When A0 = 0, microprocessor accesses the data port.
When A0 = 1, microprocessor accesses the command port.
