RTL8187B Datasheet 7. CPU Access to Endpoint Data 7.1. Control Transfer Control transfers configure and send commands to a device. Because they are so important, they employ extensive USB error checking. The host reserves a portion of each USB frame for control transfers. Control transfers consist of two or three stages. The SETUP stage contains eight bytes of USB control data. An optional DATA stage contains more data, if required.

RTL8187B Datasheet 9. EEPROM (93C46 or 93C56) Contents The RTL8187B supports the attachment of an external EEPROM. The 93C46 is a 1Kbit EEPROM (the 93C56 is a 2Kbit EEPROM). The EEPROM interface provides the ability for the RTL8187B to read from, and write data to, an external serial EEPROM device. If the EEPROM is not present, the RTL8187B initialization uses default values for the Operational Registers. Software can read and write to the EEPROM using “bit-bang” accesses via the 9346CR Register.

RTL8187B Datasheet 10. USB Packet Buffering The RTL8187B incorporates two independent FIFOs for transferring data to/from the system interface and from/to the network. The FIFOs provide temporary storage of data, freeing the host system from the real-time demands of the network. The way in which the FIFOs are emptied and filled is controlled by the FIFO threshold values in the Receive Configuration registers. These values determine how full or empty the FIFOs must be before the device requests the bus.
RTL8187B Datasheet 11. Functional Description 11.1. Transmit & Receive Operations The RTL8187B supports a new descriptor-based buffer management that will significantly lower host CPU utilization. The RTL8187B supports transmit descriptor and receive descriptor in memory. Each OUT packet contains 3-double-word transmit descriptors and each IN packet contains 4-double-word receive descriptors. 11.1.1. Transmit Tx Descriptor Format Table 27.

RTL8187B Datasheet 11.2. Rx Command The RTL8187B supports an Rx command queue to feedback the Tx state and beacon interrupt . When the Command Type (bit[31:30]) is set to 00b, it indicates Tx Beacon Interrupt. When set to 01b, it indicates Tx Close Descriptor. Table 31.

RTL8187B Datasheet 11.5. Rx Decapsulation (With RTL8187B Internal Baseband Processor) The RTL8187B continuously monitors the network when reception is enabled. When activity is recognized it starts to process the incoming data. After detecting receive activity on the channel, the RTL8187B starts to process the PLCP preamble and header based on the mode of operation. The RTL8187B checks CRC16 and CRC32, then reports if CRC16 or CRC32 has errors.
RTL8187B Datasheet 11.8. Duration Field Processing The RTL8187B supports three modes of duration field processing (selected via the DurProcMode bit in each AC_XX_TXOPQueued register). • Mode 0: Software takes full control of duration field processing. MAC has nothing to do with it. • Mode 1: DMA reads the 2-byte DURATION value in the TX descriptor and adds it to the AC_XX_TXOPQueued register.
