1. MCU Setting
Specifying the processor mode
Select the appropriate processor mode that suits your system.
Specifying the bus width
When specifying memory expansion mode or microprocessor mode,
select “16-bit” or “8-bit” for “External Data Bus Width”.
Using or not using the memory space expansion
function
Because the M306NKT-EPB does not support the memory space
expansion function, select “Normal Mode”.
Using or not using the internal reserved area
expansion
Specifies whether or not to expand the internal reserved area. Check
the box if the internal reserved area expansion bit (PM13) is “1”.
PM13= 0:
Internal RAM area: 00400h--03FFFh
Internal ROM area: D0000h--FFFFFh
PM13= 1:
Internal RAM area: 00400h--07FFFh
Internal ROM area: 80000h--FFFFFh
IMPORTANT
Notes on Selecting a Processor Mode:
z When setting single-chip mode or memory expansion mode, the level of pin CNVSS of the MCU status should
be "L". The MCU status shows the pin level of the user system.
z When setting microprocessor mode, the level of pin CNVSS of the MCU status should be "H".
z When setting memory expansion mode or microprocessor mode, pins RDY# and HOLD# of the user system
should be "H".
z When the user system is not connected, all modes are available.
