Sub clock select
Immediately after switching from main clock mode to subclock mode for the clock source, insert at least one
NOP instruction.
Bit Search Module
The BSD0, BSD1, and BDSC registers are accessed only in words.
Dbus memory
Do not allocate the code area in memory on the D-bus because no instruction fetch takes place to the D-bus.
Executing an instruction fetch to the D-bus area causes wrong data to be interpreted as code, possibly letting
the device to run out of control.
Low Power Consumption Mode
To enter the sleep or stop mode, be sure to read the standby control register (STCR) immediately after writing to it.
Precisely, use the following sequence.
Set the I flag, ILM, and ICR to, after returning from standby mode, branch to the interrupt handler having caused
the device to return.
Switch shared port function
To switch between the use as a port and the use as a dedicated pin, use the port function register (PFR). Note,
however, that bus pins are switched depending on external bus settings.
Pre-fetch
When accessing a prefetch-enabled little endian area, be sure to use word access (in 32-bit, word length) only.
Byte or halfword access results in wrong data read.
I/O port access
Ports are accessed only in bytes.
Built-in RAM
Immediately after a reset is canceled, the internal RAM allocation restricting function is still working, allowing
only four kilobytes to be used for data and for program execution irrespective of the on-chip RAM capacity.
