For example:
f
MCLK
= 12MHz, SF = 1, and f
CP
= 666.7kHz,
N
CP(4:0)
= 9.
Table 8 shows recommended CP(4:0) values for typical
MCLK frequencies.
Registers and Bit Descriptions
Eleven internal registers program and report the status
of the MAX9850. Table 9 lists all of the registers, their
addresses, and power-on-reset state. Registers 0x0
and 0x1 are read-only while all of the other registers are
read/write. Register 0xB is reserved for factory testing.
