User manual
The SPI block is identical for all EM773 parts.
Remark: The SPI block includes the full SSP feature set, and all register names use the
SSP prefix.
The SPI0 is configured using the following registers:
The SPI/SSP is a Synchronous Serial Port (SSP) controller capable of operation on a SPI,
4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus.
Only a single master and a single slave can communicate on the bus during a given data
transfer. Data transfers are in principle full duplex, with frames of 4 bits to 16 bits of data
flowing from the master to the slave and from the slave to the master. In practice it is often
the case that only one of these data flows carries meaningful data.
The EM773 has one SPI/Synchronous Serial Port controller.
1. Pins: The SPI pins must be configured in the IOCONFIG register block. In addition,
2. Power: In the SYSAHBCLKCTRL register, set bit 11 and bit 18
3. Peripheral clock: Enable the SPI0 peripheral clock by writing to the SSP0CLKDIV
4. Reset: Before accessing the SPI blocks, ensure that the SSP_RST_N bits (bit 0 and
