60
This section describes the essential steps to initialize QMC after a hard reset. Section 6.1,
“Initialization Steps,” discusses the steps required to initialize the QMC protocol, and
Section 6.2, “68MH360 T1 Example,” provides example code.
6.1 Initialization Steps
This section describes the steps required to initialize the QMC protocol.
Step 1: Initialize the SIMODE (serial interface mode) register. The SIMODE register is
defined on page 7-78 of the MC68360 User’s Manual, and page 16-114 of the MPC860
user’s manual. Table 6-1 shows the transmit buffer descriptor field descriptions.
