PET_SEQ1—PET Sequence 1 Register
(ASF Controller—B1:D8:F0)
Offset Address: F0h
Default Value: 00h
Attribute:
Size:
R/W
8 bits
This register (low byte) holds the current value of the PET sequence number. This field
is read/write-able through this register, and is also automatically incremented by the
hardware when new PET packets are generated. By policy, software should not write to
this register unless transmission is disabled.
Bit
Description
7:0 PET Sequence Byte 1 (PSEQ1_VAL) — R/W. This field provides the low byte.
8.3.14
PET_SEQ2—PET Sequence 2 Register
(ASF Controller—B1:D8:F0)
Offset Address: F1h
Default Value: 00h
Attribute:
Size:
R/W
8 bits
This register (high byte) holds the current value of the PET sequence number. This field
is read/write-able through this register, and is also automatically incremented by the
hardware when new PET packets are generated. By policy, software should not write to
this register unless transmission is disabled.
Bit
Description
7:0 PET Sequence Byte 2 (PSEQ2_VAL) — R/W. This field provides the high byte.
