Serial Audio Interface (SAI) includes two receivers and three transmitters,
master or slave capability, implementation of I
protocols; and two sets of SAI interrupt vectors
Serial Host Interface (SHI) features single master capability, 10-word receive
FIFO, and support for 8-, 16-, and 24-bit words
External Memory Interface (EMI), implemented as a peripheral supporting:
–
–
–
–
Four dedicated, independent, programmable General Purpose Input/Output
(GPIO) lines
On-chip peripheral registers memory mapped in data memory space
Three external interrupt request pins
On-Chip Emulation (OnCE) port for unobtrusive, processor speed-
independent debugging
