Detailed Errata Description

INT_X.H004 SCU Interrupts Enabled After Reset

Following a reset, the SCU interrupts are enabled by default (register

SCU_INTDIS = 0000H). This may lead to interrupt requests being triggered in

the SCU immediately, even before user software has begun to execute. In the

SCU, multiple interrupt sources are `ORed` to a common interrupt node of the

CPU interrupt controller. Due to the “ORing” of multiple interrupt sources, only

one interrupt request to the interrupt controller will be generated if multiple

sources at the input of this OR gate are active at the same time. If user software

enables an interrupt in the interrupt controller (SCU_xIC) which shares the

same node as the SCU interrupt request active after reset, it may lead to the

effect of suppressing the intended interrupt source. So, for all SCU interrupt

sources which will not be used, make sure to disable the interrupt source

(SCU_INTDIS) and clear any pending request flags (SCU_xIC.IR) before

enabling interrupts in interrupt controller.

LXBUS_X.H001 Do Not Access Reserved Locations on the LXBus

Some of the on-chip peripherals are connected via the LXBus. The EBC

controls this access by using CS7 to define the LXBus area.

The memory map lists several sections occupied by the on-chip LXBus

peripherals MultiCAN and the USIC modules.

The reserved sections within the address range 20’0000H ... 20’FFFFH shown

in the memory map are designated to additional peripherals for future

derivatives. The sizes of the reserved sections depend on the chosen device

type.

These reserved sections must not be accessed by user software nor by

debuggers. Access to these sections may lead to a CPU lock situation caused

by a bus lock and also makes the software incompatible with other derivatives.

The error mode can only be left by a reset.
