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.

Contains the transmit configuration option over-
ride bits and the TXGO bit used to start packet
transmission.
Read-only register returning 0x01 when transmit
interface is currently transmitting a packet and
0x00 when transmit interface is not transmitting.
16-bit pause value used for PAUSE packet
transmission. The pause value is in units of 512
bit times (51.2
Starting address of outgoing packet in the trans-
mit buffer. Packets added to the transmit buffer
must start at 0x0000.
Address of last byte added to the transmit
buffer. This register is managed by hardware.
Writes to this register add a byte to the transmit
buffer, set TXEND to the address of the written
byte, and increment TXSTART.
52-bit transmit status vector containing informa-
tion about the last transmitted packet including
collision count, successful transmission, total
bytes transmitted, etc.
