SCC HDLC Mode

MPC8280 PowerQUICC II Family Reference Manual, Rev. 1

22-24

Freescale Semiconductor

To program the general SCC mode register (GSMR), set the bits as described below:

•

Set MODE to HDLC mode (0b0000).

•

Configure CTSS to 1 and all other bits to zero or default.

•

Configure the DIAG bits for normal operation (0b00).

•

Configure RDCR and TDCR for 1

× clock (0b00).

•

Configure TENC and RENC for NRZ (0b000).

•

Clear RTSM to send idles between frames.

•

Set GSMR_L[ENT, ENR] as the last step to begin operation.

22.14.6.2 HDLC Bus Controller Programming Example

Except for the above discussion in Section 22.14.6.1, “Programming GSMR and PSMR for the HDLC Bus

Protocol,” use the example in Section 22.13.1, “SCC HDLC Programming Example #1.”
