4.2 Setting of the Stack Bank Selection Register (SBS)
The Mk
I
mode and Mk
II
mode are switched by stack bank selection register. Figure 4-1 shows the register
configuration.
The stack bank selection register is set with a 4-bit memory operation instruction. To use the CPU in Mk
I
mode,
initialize the register to 100
B

at the beginning of the program. To use the CPU in Mk
II
mode, initialize it to
000

Caution The CPU operates in Mk
I
mode after the RESET signal is issued, because bit 3 of SBS is set to
1. Set bit 3 of SBS to 0 (Mk
II
mode) to use the CPU in Mk
II
mode.
