When written to a logical 1, this bit inserts a Payload Type (PT) field in the outgoing header
from the TXHDR registers. When written to a logical 0, the PT field is not changed prior to
transmission.
When written to a logical 1, this bit inserts a Cell Loss Priority (CLP) bit in the outgoing
header from the TXHDR registers. When written to a logical 0, the CLP field is not changed
prior to transmission.
These bits hold the Transmit Idle Cell Payload values for outgoing idle cells.

The IDLPAY register contains the Transmit Idle Cell Payload.
Default after reset: 6A
The ERRPAT register provides the error pattern for the HEC error insertion function.
ErrHEC (bit 4) in the CGEN register (0x08) enables this function. Each bit in the
error pattern register is XORed with the corresponding bit of the calculated HEC byte
to be errored.
Default after reset: 00
The TXHDR1 register contains the first byte of the Transmit Cell Header. It controls
the header value that is inserted in the transmitted cell. This header consists of 32 bits
divided among four registers (TXHDR1–4). These bits hold the Transmit Header
values for Octet 1 of the outgoing cell. Insertion of the bits is controlled by the
HDRFIELD register (0x09).
Default after reset: 00
