To read all the first page of memory, for example, the host

processor must send the TSC2200 the command 8000

—

this

specifies a read operation beginning at Page 0, Address 0. The

processor can then start clocking data out of the TSC2200. The

TSC2200 will automatically increment its address pointer to the

end of the page; if the host processor continues clocking data

out past the end of a page, the TSC2200 will simply send back

the value FFFF

Likewise, writing to Page 1 of memory would consist of the

processor writing the command 0800

, which would specify a

write operation, with PG0 set to 1, and all the ADDR bits set

to 0. This would result in the address pointer pointing at the

first location in memory on Page 1. See the TSC2200 Memory

Map section for details of register locations. Figure 7 shows an

example of a complete data transaction between the host

processor and the TSC2200.

TSC2200 MEMORY MAP

The TSC2200 has several 16-bit registers that allow control of

the device as well as provide a location for results from the

TSC2200 to be stored until read by the host microprocessor.

These registers are separated into two pages of memory in the

TSC2200: a Data page (Page 0) and a Control page (Page 1).

The memory map is shown in Table III.
