STROBE pulses must be applied to latch the data
into the CS6422.
Since the MCR is a shift register, the STROBE can
be run arbitrarily slowly with a duty cycle limited
only by the minimum high and low time specified
in “Switching Characteristics”. The Microcontrol-
ler Interface is polled at 125 µs intervals, so regis-
ter writes must be spaced at least 125 µs apart or
the register contents may be overwritten.

The six control registers accessible through the
MCR are described in detail in the following tables.
These registers are addressed by bits b3-0 of the
MCR. Bit ‘b0’ must always be ‘0’. Table 2 shows
the register map with the default settings. Tables 3
through 8 show the control registers in more detail.
The Register Map at the top of each register de-
scription shows the names of all the bits, with their
reset values below the bitfield name. The reset val-
ue can also be found in the Word column of the bit-
field summary as indicated by an ‘*’.
