Preliminary
5.6.30.9
IRQA Edge Pin (IRQA Edg)—Bit 0
This bit controls whether the external IRQA interrupt is edge- or level-sensitive. During Stop and Wait
modes, it is automatically level-sensitive.
0 = IRQA interrupt is a low-level sensitive (default)
1 = IRQA interrupt is falling-edge sensitive.
5.7 Resets
5.7.1
Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address whenever RESET is asserted. The reset
vector will be presented until the second rising clock edge after RESET is released.
5.7.2
ITCN After Reset
After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled,
except the core IRQs with fixed priorities:
Illegal Instruction
SW Interrupt 3
HW Stack Overflow
Misaligned Long Word Access
SW Interrupt 2
SW Interrupt 1
SW Interrupt 0
SW Interrupt LP
These interrupts are enabled at their fixed priority levels.
Part 6 System Integration Module (SIM)
6.1 Overview
The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls
distribution of resets and clocks and provides a number of control features. The system integration module
is responsible for the following functions:
Reset sequencing
Clock generation & distribution
Stop/Wait control
Pull-up enables for selected peripherals
System status registers
Registers for software access to the JTAG ID of the chip
