5 System Control Unit
The System Control Unit (SCU) of the TC1796 handles system control tasks. All the
system functions described in this chapter are tightly coupled; thus, they are
conveniently handled by one unit, the SCU.
The system tasks of the SCU that are covered in this chapter are:
• Power Management (see Page 5-2)
• Configuration Input Sampling (see Page 5-8)
• External Request Unit (see Page 5-9)
• Special System Interrupts (see Page 5-35)
• On-chip SRAM Parity Control (see Page 5-37)
• Pad Driver Temperature Compensation Control (see Page 5-41)
• Die Temperature Sensor (see Page 5-48)
• GPTA1 Input IN1 Control (see Page 5-49)
• Pad Test Mode Control (see Page 5-50)
• Emergency Stop Output Control for GPTA and MSC (see Page 5-57)
• Analog Input 7 Testmode (see Page 5-60)
• Miscellaneous SCU Registers (see Page 5-64)
• SCU Registers and Address Map (see Page 5-61)
