• Manufacturer Part Number: S912XEQ384J3MALR
• Description: S912XEQ Series 16 Bit 50 Mhz 384 KB Flash 24 KB Ram Microcontroller - LQFP-112
• Manufacturer: Freescale Semiconductor

The trigger priorities described in
on the lower channel number (0,1,2,3) has priority. The SC[3:0] encoding ensures that a match leading to
final state has priority over all other matches.

Read: If COMRV[1:0] = 10
Write: If COMRV[1:0] = 10 and S12XDBG is not armed.
This register is visible at 0x0027 only with COMRV[1:0] = 10. The state control register three selects the
targeted next state whilst in State3. The matches refer to the match channels of the comparator match
control logic as depicted in
by setting the comparator enable bit in the associated DBGXCTL control register.
