USB FUNCTION
The 7641 Group MCU is equipped with a USB Function Control
Unit (USB FCU). This USB FCU allows the MCU to communicate
with a host PC using a minimum amount of the MCU power. This
built-in USB FCU complies with USB Standard Specification Ver-
sion 1.1 that supports four transfer types: Control Transfer,
Isochronous Transfer, Interrupt Transfer, and Bulk Transfer. This
built-in USB FCU performs the data transfer error detection and
transfer retry operation by hardware. The default transfer mode of
the USB FCU is bulk transfer mode at reset. The user must set the
USB FCU for the required transfer mode by software.
The USB FCU has five endpoints (Endpoint 0 to Endpoint 4). The
EPINDEX bit selects one of these five endpoints for the USB FCU
to use. Each endpoint has IN (transmit) FIFO and OUT (receive)
FIFO. To use the USB FCU, the USB enable bit (USBC7) must be
set to “1”. There are two USB related interrupts supported for this
MCU: USB Function Interrupt and USB SOF Interrupt.
Figure 36 shows the USB FCU (USB Function Control Unit) block
diagram. The USB FCU consists of the SIE (Serial Interface En-
gine) performing the USB data transfer, GFI (Generic Function
Interface) performing USB protocol handing, SIU (Serial Engine
Interface Unit) performing a received address and endpoint de-
coding, MCI (Microcontroller Interface) handling the MCU
interface or performing address decoding and synchronization of
control signals, and the USB transceiver.
