Caution Since SBS. 3 is set to “1” after a RESET signal is generated, the CPU operates in the Mk
I mode. When executing an instruction in the Mk II mode, set SBS. 3 to “0” to select the
Mk II mode.
4.2 Setting Method of Stack Bank Select Register (SBS)
Switching between the Mk I mode and Mk II mode can be done by the SBS. Figure 4-1 shows the format.
The SBS is set by a 4-bit memory manipulation instruction. When using the Mk I mode, the SBS must be
initialized to 1000B
at the beginning of a program. When using the Mk II mode, it must be initialized to 0000B.
