12.5. Receive Status and Control Registers
The CP2200/1 receive interface is controlled and managed through the registers in Table 16. The current packet
registers provide information about the next packet to be unloaded from the receive buffer (the oldest packet
received).
Table 16. Receive Status and Control Register Summary
Register
Long Name
Address
Description
RXCN
Receive Interface Control
0x11
Contains receive interface control bits such as RXSKIP,
RXCLRV, RXRST, and RXINH.
RXSTA
Receive Interface Status
0x12
Indicates when the receive interface is busy receiving a
frame and when the current packet has been completely
read from the buffer.
RXAUTORD Receive AutoRead
0x01
Provides an efficient method of reading entire packets
sequentially from the receive buffer.
RXFILT
Receive Filter Configuration
0x10
Specifies the type of packets can pass through the
receive filter.
RXHASHH
RXHASHL
Multicast Hash Table
0x0E
0x0F
16-bit Hash Table used to filter multicast packets.
CPINFOH
CPINFOL
Current Packet Information
0x1D
0x1E
Specifies information about the current packet such as
broadcast/multicast, CRC errors, etc.
CPLENH
CPLENL
Current Packet Length
0x1F
0x20
Specifies the length of the current packet in the receive
buffer (in bytes).
CPADDRH
CPADDRL
Current Packet Address
0x21
0x22
Specifies the starting address of the current packet in
the receive buffer.
