Hardened SPI IP Core
Every MachXO2 device has a hard SPI IP core that can be configured as a SPI master or slave. When the IP core
is configured as a master it will be able to control other SPI enabled chips connected to the SPI bus. When the core
is configured as the slave, the device will be able to interface to an external SPI master. The SPI IP core on
MachXO2 devices supports the following functions:
SCLI
SCLO
SCLOEN
SDAI
SDAO
SDAOEN
IRQO
• Configurable Master and Slave modes
• Full-Duplex data transfer
• Mode fault error flag with CPU interrupt capability
• Double-buffered data register
• Serial clock with programmable polarity and phase
• LSB First or MSB First Data Transfer
• Interface to custom logic through 8-bit WISHBONE interface
