Transmit User Cell Filter # 2 - Pattern Register - Header Byte 1:
The User Cell filtering criteria (for Transmit User Cell Filter # 2) is
defined based upon the contents of 9 read/write registers.
These registers are the four "Transmit ATM Cell Processor Block -
Transmit User Cell Filter # 2 - Pattern Registers", the four "Transmit
ATM Cell Processor Block - Transmit User Cell Filter # 2 - Check Reg-
isters" and the "Transmit ATM Cell Processor Block - Transmit User
Cell Filter # 2 Control Register.
This READ/WRITE register, along with the "Transmit ATM Cell Proces-
sor Block - Transmit User Cell Filter # 2 - Check Register - Header
Byte 1" permits the user to define the User Cell Filtering criteria for
"Octet # 1" of the incoming User Cell.
The user will write the header byte pattern (for Octet 1) that he/she
wishes to use as part of the "User Cell Filtering" criteria, into this reg-
ister.
The user will also write in a value into the "Transmit ATM Cell Proces-
sor Block - Transmit User Cell Filter # 2 - Check Register - Header
Byte 1" that indicates which bits within the first octet of the incoming
cells are to be compared with the contents of this register.
