2.6.12 C_MASK_L/HConstant for CRC Check
The C_MASK constant is used for the CRC check. The values for CRC16/CRC32 modes
are shown in Table 21. For software testing, an incorrect initialization can be used to force
a receive-CRC error.
2.6.13 T_F_MASK and R_F_MASKTx/Rx Framer Bit Masks
T_F_MASK and R_F_MASK select what bits are active in the B channel. Any combination
of the 8 bits may be chosen. Figure 14 shows the Telds for the framer masks; Table 22
describes the masking for sending and receiving. These parameters must be initialized if
QH mode is selected.

2.6.14 Other Channel Parameters
All other parameters do not need to be accessed by the user in normal operationthey only
need to be initialized every time the QH receiver or transmitter channel is restarted. Section
2.14, òQH Parameters Initialization Summary,ó lists initial values for these parameters. The
initial value of parameters not described is unimportant.

0 Mask the corresponding TXD bit— ‘1’ is
driven on the transmit line.
1 Bit ‘transmitted—data will be transmitted.
0 Mask the corresponding RXD bit—the bit
is not received.
1 Bit received— data will be shifted into the
receiver.
