CHAPTER 5 FUNCTION DESCRIPTION
5.1 OTG (On-The-Go)
A dual-role OTG device that has the following features and characteristics:
Liminted Hos capability
High/Full-speed operation as peripheral
High/Full-speed support as host
Targeted Peripheral List
Session Request Protocol
Host Negotiation Protocol
One Mini-AB receptacle
Minimum 8mA output on VBUS
5.2 SIE (Serial Interface Engine)
The Serial Interface Engine, which contains the USB PID and address recognition logic, and other sequencing
and state machine logic to habdle USB packets and transactions.
5.3 EPFIFO (Endpoint FIFO)
Endpoint FIFO includes Control FIFO (FIFO0), Interrupt FIFO (FIFO3) and Bulk In/Out FIFO (BULKFIFO).
Control FIFO
FIFO of control endpoint 0.
It is 64-bytes FIFO, and it is used for endpoint 0 data transfer.
64-bytes depth FIFO of endpoint 3 for status interrupt.
It can be in the TX mode or RX mode:
a. It contains ping-pong FIFO (512 bytes each bank) for transmit/receive data
continuously.
b. It can be directly accessed by Uc.
Interrupt FIFO
Bulk In/Out FIFO
c. Support automatic hardware SmartMedia ECC error correction.
5.4 SSI (Synchronous Serial Interface)
The Synchronous Serial Interface provides serial data in and out for communication with serial fingerprint
sensor The SSI uses following pins: SSICLK, SSIDO and SSIDI.
SSICLK: Synchronous Serial Interface Clock
SSIDO:
Synchronous Serial Interface Data Output
SSIDI:
Synchronous Serial Interface Data Input
5.4.1 One Byte Receive/Transmit Mode
GL824 provides a programmable synchronous serial interface. The SSI not only supports both clock normal
and clock opposite phases but also supports MSB or LSB data formats. One Byte Receive/Transmit timing
