Zarlink Semiconductor Inc.
12.3.9.5
DTST – Data read back register
CPU Address: hF04
Accessed by CPU and serial interface (RO)
This register provides various internal information as selected in DPST bit[4:0]. Refer to the PHY Control
Application Note.
When bit is 1:
Bit [0] – Flow control enable
Bit [1] – Full duplex port
Bit [2] – Fast Ethernet port
Bit [3] – Link is down
Bits [7:4] for GE ports only:
Bit [4] – Giga port
Bit [5] – Signal detect (PCS mode only)
Bit [6] - Reserved
Bit [7] – Module detected (for hot swap purpose)
12.3.9.6
DA – Dead or Alive Register
CPU Address: hFFF
Accessed by CPU and serial interface (RO)
Always return 8’h DA. Indicate the CPU interface or serial port connection is good.
12.4
TBI Registers
Two sets of TBI registers are used for configure the two Gigabit ports if they are operating in TBI mode. These TBI
registers are located inside the switching chip and they are accessed through the MII command and MII data
registers.
