There is no Basic command to change CPU mode on MSX turbo R by default.
Several music drivers and other small programs that support several CALL
statements do have a CALL Z80 or CALL R800 built-in to switch between Z80
and R800 DRAM mode.
To change CPU modes you can use this in your basic program:
10 DATA 3A,63,F6,FE, 02,CA,8A,2F, 3A,2D,00,FE, 03,D8,3A,F8, F7,E6,03,C6,
80,C3,80,01
20 FOR I=0 TO 23: READ A$: POKE &HF975+I,VAL("&H"+A$): NEXT I: DEF USR=&HF975
30 A=USR(0) ' Z80
40 A=USR(1) ' R800 ROM
50 A=USR(2) ' R800 DRAM
