LAN Controller Registers (B1:D8:F0) (Desktop and Mobile Only)
8.3.10
RETRAN_PCL—Retransmission Packet Count Limit
Register (ASF Controller—B1:D8:F0)
Offset Address: EBh
Default Value: 03h
Attribute:
Size:
R/W
8 bits
This register defines the number of packets that are to be sent due to an SOS.
Bit
Description
7:0
Retransmission Packet Count Limit (RPC_VAL) — R/W. This field provides the
number of packets to be sent for all SOS packets that require retransmissions.
8.3.11
ASF_WTIM1—ASF Watchdog Timer 1 Register
(ASF Controller—B1:D8:F0)
Offset Address: ECh
Default Value: 01h
Attribute:
Size:
R/W
8 bits
This register is used to load the low byte of the timer. When read, it reports the
decrementing value. This register is not intended to be written by software, but should
be configured appropriately in the EEPROM location for this register default. Timer Start
ASF SMBus transactions will load values into this register. Once the timer has expired
(0000h), the timer will be disabled (EDG_ENA=0b) and the value in this register will
remain at 00h until otherwise changed.
Bit
Description
7:0
ASF Watchdog Timer 1 (AWD1_VAL) — R/W. This field provides the low byte of the
ASF 1-second resolution timer. The timer is accurate to +0 seconds, –0.336 seconds.
8.3.12
ASF_WTIM2—ASF Watchdog Timer 2 Register
(ASF Controller—B1:D8:F0)
Offset Address: EDh
Default Value: 00h
Attribute:
Size:
R/W
8 bits
This register is used to load the high byte of the timer. When read, it reports the
decrementing value. This register is not intended to be written by software, but should
be configured appropriately in the EEPROM location for this register default. Timer Start
ASF SMBus transactions will load values into this register. Once the timer has expired
(0000h), the timer will be disabled (EDG_ENA=0b) and the value in this register will
remain at 00h until otherwise changed.
Bit
Description
ASF Watchdog Timer 2 (AWD2_VAL) — R/W. This field provides the high byte of
7:0 the ASF 1-second resolution timer. The timer is accurate to +0 seconds, –0.336
seconds.
