Serial Peripheral Interface (SPI)
7.6
SPI Control Registers
The Control Registers have a READ/WRITE access (see Chapter 7.5):
⢠The âPORâ value is defined by the register content after a POR or device Reset
â The default value of all control registers is 0000 0000B with the exception of CONFIG_CTRL
â The default value of the CONFIG_CTRL register is 0000 0010B
⢠One 16-bit SPI command consists of two bytes (see Figure 25 and Figure 26), i.e.
â an address byte
â 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 â0â (= READ ONLY).
⢠Writing to a register is done byte wise by setting the SPI bit 7 to â1â.
