7.3.2 100Base-TX Full Duplex (bit 1.14)
The STA reads this bit to learn if the ICS1893BF can support 100Base-TX, full-duplex operations. The
ISO/IEC specification requires that the ICS1893BF must set bit 1.14 to logic:
Zero if it cannot support 100Base-TX, full-duplex operations.
One if it can support 100Base-TX, full-duplex operations. (For the ICS1893BF, the default value of bit
1.14 is logic one, in that the ICS1893BF supports 100Base-TX, full-duplex operations.)
Bit 1.14 is a Command Override Write bit, which allows an STA to alter the default value of this bit. [See the
description of bit 16.15, the Command Override Write Enable bit, in Section 7.11, “Register 16: Extended
7.3.3 100Base-TX Half Duplex (bit 1.13)
The STA reads this bit to learn if the ICS1893BF can support 100Base-TX, half-duplex operations. The
ISO/IEC specification requires that the ICS1893BF must set bit 1.13 to logic:
Zero if it cannot support 100Base-TX, half-duplex operations.
One if it can support 100Base-TX, half-duplex operations. (For the ICS1893BF, the default value of bit
1.13 is logic one. Therefore, when an STA reads the Status Register, the STA is informed that the
ICS1893BF supports 100Base-TX, half-duplex operations.)
This bit 1.13 is a Command Override Write bit, which allows an STA to alter the default value of this bit.
[See the description of bit 16.15, the Command Override Write Enable bit, in Section 7.11, “Register 16:
7.3.4 10Base-T Full Duplex (bit 1.12)
The STA reads this bit to learn if the ICS1893BF can support 10Base-T, full-duplex operations. The
ISO/IEC specification requires that the ICS1893BF must set bit 1.12 to logic:
Zero if it cannot support 10Base-T, full-duplex operations.
One if it can support 10Base-T, full-duplex operations. (For the ICS1893BF, the default value of bit 1.12
is logic one. Therefore, when an STA reads the Status Register, the STA is informed that the ICS1893BF
supports 10Base-T, full-duplex operations.)
This bit 1.12 is a Command Override Write bit, which allows an STA to alter the default value of this bit.
[See the description of bit 16.15, the Command Override Write Enable bit, in Section 7.11, “Register 16:
7.3.5 10Base-T Half Duplex (bit 1.11)
The STA reads this bit to learn if the ICS1893BF can support 10Base-T, half-duplex operations. The
ISO/IEC specification requires that the ICS1893BF must set bit 1.11 to logic:
Zero if it cannot support 10Base-T, half-duplex operations.
One if it can support 10Base-T, half-duplex operations. (For the ICS1893BF, the default value of bit 1.11
is logic one. Therefore, when an STA reads the Status Register, the STA is informed that the ICS1893BF
supports 10Base-T, half-duplex operations.)
Bit 1.11 of the ICS1893BF Status Register is a Command Override Write bit., which allows an STA to alter
the default value of this bit. [See the description of bit 16.15, the Command Override Write Enable bit, in
