System Integration Module (SIM)
13.1 Introduction
This section describes the system integration module (SIM), which supports up to 24 external and/or
internal interrupts. Together with the central processor unit (CPU), the SIM controls all microcontroller unit
(MCU) activities. A block diagram of the SIM is shown in
that coordinates CPU and exception timing.
The SIM is responsible for:
13.2 RST and IRQ Pins Initialization
RST and IRQ pins come out of reset as PTA3 and PTA2 respectively. RST and IRQ functions can be
activated by programing CONFIG2 accordingly. Refer to

Table 13-1. Signal Name Conventions
Buffered clock from the internal, RC or XTAL oscillator circuit.
The BUSCLKX4 frequency divided by two. This signal is again
divided by two in the SIM to generate the internal bus clocks
(bus clock = BUSCLKX4 ÷ 4).
