29.4.6 FIFO
(1) Overview
The transmit and receive FIFOs of the SIOF have the following features.
•
16-stage 32-bit FIFOs for transmission and reception
•
The FIFO pointer can be updated in one read or write cycle regardless of access size of the
CPU and DMAC. (One-stage 32-bit FIFO access cannot be divided into multiple accesses.)
(2) Transfer
Request
The transfer request of the FIFO can be issued to the CPU or DMAC as the following interrupt
sources.
•
FIFO transmit request: TDREQ (transmit interrupt source)
•
FIFO receive request: RDREQ (receive interrupt source)
The request conditions for FIFO transmit or receive can be specified individually. The request
conditions for the FIFO transmit and receive are specified by the bits TFWM[2:0] and the bits
RFWM[2:0] in SIFCTR, respectively. Table 29.11 and table 29.12 summarize the conditions
specified by SIFCTR.
