Configuration Mode
Bits N[1:0] specify the number of accessed registers, as defined in
Bits A[4:0] specify the address of the first register to access. This address is then incremented internally
by N after each data byte transfer.
R/W specifies the type of operation:
Thus, this bit is associated with the presence of information on MOSI (when writing) or MISO (when
reading).

a slave. A received byte is considered internally on the eighth falling edge of SCLK. Consequently, the last
received bits, which do not form a complete byte, are lost.

If several SPI accesses are done, a high and low level is applied to CONFB, and so on. By applying a high
level to STROBE, the MC33696 never enters standby mode. If there is no way to configure the level on
STROBE, the time interval between two SPI accesses must be less than one digital clock period T
