Serial Peripheral Interface (SPI)
7.6
SPI Control Registers
The Control Registers have a READ/WRITE access (see Chapter 7.5):
• The ‘POR’ value is defined by the register content after a POR or device Reset
– The default value of all control registers is 0000 0000_B with the exception of CONFIG_CTRL
– The default value of the CONFIG_CTRL register is 0000 0011_B
• One 16-bit SPI command consists of two bytes (see Figure 25 and Figure 26), i.e.
– an address byte
– followed by a data byte
• The control bits are not cleared or changed automatically by the device. This must be done by the
microcontroller via SPI programming.
• Reading a register is done byte wise by setting the SPI bit 7 to “0” (= READ ONLY).
• Writing to a register is done byte wise by setting the SPI bit 7 to “1”.
