FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
TEST MODE
Bit 16 is reserved for placing the device into a special IC
Test mode. It is used to confirm various internal functions.
SPI RESPONSES
Response Protocol (Data out of SO).
RESET/SLEEP
When the Reset (RST) input is active (logic [0]), all internal
registers are cleared, thereby placing the device in Sleep
mode and upon the RST input returning to the inactive state
(logic [1]) the MC33884 remains in Sleep mode. A SPI
command, received from the microprocessor, is necessary to
command the device out of Sleep mode.
