OVERVIEW
The High Speed Serial Peripheral Interface (HS_SPI) can interface the serial data transfer. HS_SPI has two
8/16/32-bit shift registers for transmission and receiving, respectively. During an HS_SPI transfer, data is
simultaneously transmitted (shifted out serially) and received (shifted in serially). HS_SPI supports the protocols
for National Semiconductor Microwire and Motorola Serial Peripheral Interface.
FEATURES
The features of the HS_SPI are:
Supports full duplex
8/16/32-bit shift register for TX/RX
8-bit prescale logic
3 clock source
Supports 8bit/16bit/32bit bus interface
Supports the Motorola HS_SPI protocol and National Semiconductor Microwire
Two independent transmit and receive FIFOs, each 16 samples deep by 32-bits wide
Master-mode and Slave-mode
Receive-without-transmit operation
