USB Suspend Interrupt
A USB Suspend Interrupt is generated when the USB FCU does not detect any bus activity on D+/D- (in J-
state) for at least 3ms.
The USB Suspend Interrupt Control register (SUSPIC) contains the USB Suspend Interrupt request bit and
interrupt priority select bits that are used to enable the interrupt and set its software priority level.
USB Endpoint FIFOs
The USB FCU has a built-in 3.25 K bytes FIFO as an endpoint buffer. The EP0 (control endpoint) FIFO
occupies a fixed location (from 3K – 3.25K) with fixed buffer sizes (128 bytes each) for its IN and OUT data
transfers. The other 8 endpoints (EP1 to EP4 IN and OUT) share a 3K bytes buffer. Each endpoint’s FIFO
size and starting location (64 bytes) are programmable by the user. The sum of the 8 endpoint FIFOs can
not exceed 3K bytes (3072 bytes).
Note: Throughout the USB Block specification, “data packet” is generally used when continuous mode is
disabled; “data set” (one or more data packets) is generally used when continuous mode is enabled. If a
description applies for both noncontinuous mode and continuous mode, “data set” is used.
Throughout the whole USB Block Specification, “FIFO” and “Buffer” are generally interchangeable terms.
EP0 FIFO Operation
The CPU writes data to the EP0 IN FIFO Data Register. The write pointer automatically increments by 2 in
word accessing mode or by 1 in byte accessing mode after a write. The CPU must only write data to the
EP0 IN FIFO Data Register and “1” to the SET_IN_BUF_RDY bit of the EP0 CSR when the IN_BUF_RDY
flag is a “0”. When a NULL packet is required to complete a control read request, the CPU must write “1” to
the SET_IN_BUF_RDY bit of EP0_CSR without writing data to the EP0 IN FIFO Data Register.
Continuous transfer modes are available for EP0 Control Transfers.
EP0 IN FIFO with control read continuous transfer mode disabled
The CPU writes “1” to the SET_IN_BUF_RDY bit of the EP0 CSR after the CPU finishes writing a data
packet to the FIFO, this updates the IN_BUF_RDY flag to “1”. The USB FCU updates the IN_BUF_RDY
flag to “0” after the packet has been successfully transmitted to the host.
EP0 IN FIFO with control read continuous transfer mode enabled
The CPU writes “1” to the SET_IN_BUF_RDY bit of the EP0 CSR after the CPU finishes writing a data
set (up to 128 bytes) to the FIFO. This updates the IN_BUF_RDY flag to “1”. The USB FCU sends out
data packets equal to the EP0 MAXP size one at a time, except for the last packet if the data set in the
FIFO is not a multiple of EP0 MAXP. In this case the USB FCU sends a short packet. The USB FCU
updates the IN_BUF_RDY flag to “0” after the data set has been successfully transmitted to the host.
The CPU reads data from EP0 OUT FIFO Data Register. The read pointer automatically increments by 2
in word accessing mode or by 1 in byte accessing mode after a read. The CPU must only read data from
the EP0 OUT FIFO when the OUT_BUF_RDY flag of the EP0_CSR is “1”.
When a SETUP packet is received, an EP0 interrupt is generated (both OUT_BUF_RDY and SETUP
flags are set) regardless of the continuous transfer mode bit setting.
EP0 OUT FIFO with control write continuous transfer mode disabled
The USB FCU updates the OUT_BUF_RDY flag to “1” after it has successfully received a data packet
from the host. The CPU writes “1” to CLR_OUT_BUF_RDY after the data packet has been unloaded from
the FIFO by the CPU (updates the OUT_BUF_RDY flag to a “0”).
