entered the MOSI pin starting with Bit15, followed by Bit14,
Bit13, etc., to Bit0. For each fall of the SCLK signal, with CS
held in a logic low state, a data bit is loaded into the shift
register per the tidbit MOSI state.The shift register is full after
sixteen bits of information have been entered.
MISO PIN
the shift register. The MISO pin remains in a high impedance
state until the CS pin goes to a logic low state. The MISO pin
changes state on the rising edge of SCLK and reads out on
the falling edge of SCLK. The MOSI/MISO shifting of data
follows a first-in-first-out protocol with both input and output
words transferring the MSB first.

Control and Status Reporting of the 33389
33389, while the 33389 reports its status to the MCU. Major
data for control and status reporting are summarized here:
• SPI initialization during start up
• 33389 control during operation
• Watchdog triggering
• Reading status registers of the 33389
Control Data
33389. A control word includes an address of a control
register and the appropriate data (see
the following data will be transferred. Please see
Registers Descriptions on page
• 33389 mode control
• Supply control
• Forced wake-up timing
• Cyclic sense control
• Watchdog control
• Transceiver control
Status Data
MCU. After receiving a valid register address from the MCU,
the 33389 returns the appropriate status. Some of the major
status data are listed below:
• Current operation mode status
• Wake-up sources
• Reset status
• Error status
• Over temperature status
• Transceiver status
Data Transfer
two bytes.The structure of the transferred information is the
same as for control and status reporting. The address field A5
to A0 (Bit 15 to Bit 10) contains the address of a control or
status register in the 33389. RW (Bit 9 and Bit 8) contains the
read/write flag for the data field. The parity field is located at
P3 to P0 (Bit 7 to Bit 4). The data field D3 to D0 (Bit 3 to Bit
0) is part of the two-byte data word. Please see
