2.17 QH Mode Hardware Initialization
The proper initialization order of the internal QH302 modules begins with the external pins,
then the serial interface, and the SCCs last. The following shows the proper hardware
initialization sequence for QH operation:
1. Program the parallel I/O to select the pins needed for the application.
2. Select SCC2 pins for dedicated mode to connect SCC2 to the external pins to operate
as a DTE connection.
3. Program the serial interface registers to conTgure the serial channel physical
interface:
SIMASK:write 0xFFFF to SIMASK register.
SIMODE: select the IDL/GCI mode using the MS[0,1] bits.
Route B1 and B2 to SCC1, that is, [B1RB,B1RA] = 01, [B2RB, B2RA] = 01.
Route D channel to SCC3, that is, [DRB,DRA] = 11 and MSC3 = 0.
Route SCC2 to the NMSI pins, that is, MSC2 = 1.
All other bits are user-deTned.
4. Program the QH parameters in the dual-port RAM.
5. Program SCON1 and SCON3 to 0x3000 to enable operating from the SI clock.
