TSC2302
SLAS394–JULY 2003
To read all the first page of memory, for example, the host processor must send the TSC2302 the command
0x8000 - this specifies a read operation beginning at page 0, address 0. The processor can then start clocking
data out of the TSC2302. The TSC2302 automatically increments its address pointer to the end of the page; if
the host processor continues clocking data out past the end of a page, the TSC2302 simply sends back the
value 0xFFFF.
Continuous writing is generally not recommended for the control registers, but for the coefficients of bass-boost
filter coefficient registers, continuous writing works. Writing to these registers consists of the processor writing the
command 0x10E0, which specifies a write operation, with PG1 set to 1, and the ADDR bits set to 07h. This
results in the address pointer pointing at the location of the first bass-boost coefficient in memory see
Table 2(Page 2). See the section on the TSC2302 memory map for details of register locations
