TSC2101 Memory Map
The TSC2101 has several 16-bit registers which allow control of the device as well as providing a location for
results from the TSC2101 to be stored until read by the host microprocessor. These registers are separated
into four pages of memory in the TSC2101: a data page (page 0), control pages (page 1 and page 2) and a buffer
data page (page 3). The memory map is shown in Table 6.
