CHAPTER 5 FUNCTION DESCRIPTION
UTM
The USB 2.0 Transceiver Macrocell is the analog circuitry that handles the low level USB protocol and signaling,
and shifts the clock domain of the data from the USB 2.0 rate to one that is compatible with the general logic.
SIE
The Serial Interface Engine, which contains the USB PID and address recognition logic, and other sequencing
and state machine logic to handle USB packets and transactions.
EPFIFO
Endpoint FIFO includes Control FIFO (FIFO0), interrupt FIFO (FIFO3), Bulk In/Out FIFO (BULKFIFO)
Control FIFO
FIFO of control endpoint 0.
It is 64-byte FIFO, and it is used for endpoint 0 data transfer.
Interrupt FIFO
64-byte depth FIFO of endpoint 3 for status interrupt
Bulk In/Out FIFO
It can be in the TX mode or RX mode:
1. It contains ping-pong FIFO (512 bytes each bank) for transmit/receive data continuously.
2. It can be directly accessed by Uc
3. Automatic hardware SmartMedia ECC error correction support
MHE
It contains 4 MIFs (Media Interface)
MIFs
1. SmartMedia / xD/ Flash
2. SD / MMC
3. MemoryStick
4. MemoryStick PRO
Remote wakeup
Support Card insert wakeup while suspend.
External reset circuit
Non-inverting, Schmitt input with weak pull-up using DVDD power.
CLOCK Source Selection
It selects 12/48 MHz input by exterior pull resistor.
