Serial Peripheral Interface (SPI)
SPI is a 4-wire, full-duplex serial communication interface between a master device and one or more slave devices. The
CY7C637xx SPI circuit supports byte serial transfers in either Master or Slave modes. The block diagram of the SPI circuit is
shown in Figure 17-1. The block contains buffers for both transmit and receive data for maximum flexibility and throughput. The
CY7C637xx can be configured as either an SPI Master or Slave. The external interface consists of Master-Out/Slave-In (MOSI),
Master-In/Slave-Out (MISO), Serial Clock (SCK), and Slave Select (SS). Writes to the SPI Data Register (see Figure 17-2) load
the transmit buffer, while reads from this register read the receive buffer contents.
SPI modes are activated by setting the appropriate bits in the SPI Control Register, as described below.
