4.1 Differences between Mk
I
Mode and Mk
II
Mode
The CPU of the
m
PD750108 has two modes (Mk
I
mode and Mk
II
mode) and which mode is used is selectable.
Bit 3 of the stack bank selection register (SBS) determines the mode.
Mk
I
mode:
This mode has the upward compatibility with the 75X series.
It can be used in the 75XL CPUs having a ROM of up to 16 KB.
This mode is not compatible with the 75X series.
It can be used in all 75XL CPUs, including those having a ROM of 16 KB or more.
Mk
II
mode:
Table 4-1 shows the differences between Mk
I
mode and Mk
II
mode.

Caution Mk
II
mode can be used to support a program area larger than 16K bytes in the 75X series or 75XL
series. This mode enhances a software compatibility with products whose program area is larger
than 16K bytes. If Mk
II
mode is selected, when the subroutine call instruction is executed, the
number of stack bytes (use area) will be increased by one byte for each stack, compared to Mk
I
mode. When a CALL !addr or CALLF !faddr instruction is executed, it takes one more machine
cycle. Therefore, Mk
I
mode should be used for applications for which RAM efficiency or
processing capabilities is more critical than a software compatibility.
