TSC2301
SLAS371D – SEPTEMBER 2002 – REVISED AUGUST 2004
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 3
(Page 2). See the section on the TSC2301 memory map for details of register locations
