11.5. Transmit Status and Control Registers
The CP2200 transmit interface is controlled and managed through the registers in Table 14. After each packet is
transmitted, information about the last transmitted packet can be obtained from the 52-bit transmit status vector
accessible through the TXSTA0 — TXSTA6 registers. The transmit status vector is described in Table 15.
Table 14. Transmit Status and Control Register Summary
Register
Long Name
Address
Description
TXCN
Transmit Control
0x53
Contains the transmit configuration option over-
ride bits and the TXGO bit used to start packet
transmission.
TXBUSY
Transmit Busy Indicator
0x54
Read-only register returning 0x01 when transmit
interface is currently transmitting a packet and
0x00 when transmit interface is not transmitting.
TXPAUSEH
TXPAUSEL
Transmit Pause High and Low Bytes
0x55
0x56
16-bit pause value used for PAUSE packet
transmission. The pause value is in units of 512
bit times (51.2
μs).
TXSTARTH
TXSTARTL
Transmit Data Starting Address High
and Low Bytes
0x59
0x5A
Starting address of outgoing packet in the trans-
mit buffer. Packets added to the transmit buffer
must start at 0x0000.
TXENDH
TXENDL
Transmit Data Ending Address High
and Low Bytes
0x57
0x58
Address of last byte added to the transmit
buffer. This register is managed by hardware.
TXAUTOWR Transmit Data AutoWrite
0x03
Writes to this register add a byte to the transmit
buffer, set TXEND to the address of the written
byte, and increment TXSTART.
TXSTA6
TXSTA5
TXSTA4
TXSTA3
TXSTA2
TXSTA1
TXSTA0
Transmit Status Vector
0x5C
0x5D
0x5E
0x5F
0x60
0x61
0x62
52-bit transmit status vector containing informa-
tion about the last transmitted packet including
collision count, successful transmission, total
bytes transmitted, etc.
