* Description :
*
This is a shell program for using a stand-alone 68HC16 without any external memory. The internal 1K RAM
*
is put into bank $0F to maintain 68HC11 code compatibility. This program was written with software
*
provided in the Motorola 68HC16 Evaluation Kit.

;This routine sets up the QSPI microsequencer to operate on its own.
;The sequencer will read all eight channels of a MAX192 each time
;it is triggered. The A/D converter results will be left in the
;receive data RAM. Each 16 bit receive data RAM location will
;have a leading zero, 10 + 2 bits of conversion result and three zeros.
