TERMINAL MODE RELATED
SUMMARY:
Set  the Low Speed Data (LSD) mode.
STEP PROCEDURE 
1Note:
MCU 5000A does not support LSD mode.  Be sure, therefore, to set all LSD mode settings to 
OFF (0000H)
.  If change is necessary for any reason, follow the steps described below.
Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address12AH 
and 12BH
[1] Addresses (hexadecimal values) on setting the LSD mode.
The LSD mode is set in hexadecimal values by dividing the 16 bits (b0 to b15) into 
the upper-half and lower-half 8 bits.
ADDRESS  LSD  MODE
12AH Lower-half 8 bits setting address (b0 to b7)
12BH Upper-half 8 bits setting address (b8 to b15)
xi:
System parameter values See  below:

MBE MODE SETTING
TERMINAL MODE RELATED
SUMMARY: 
MCU 5000A uses MBE command to utilize NECs original expansion devices.
STEP PROCEDURE 
Note:
Set the MBE mode to ON (01H 00H)
 as a general rule.  If change is necessary for any reason, 
follow the steps described below.
1 Enter the following command.
SSPR__ n1 =  x1 __n2 = x2 __ … ni = xi … ¿
ni:
System parameter address136H 
and 137H
[1] Addresses (hexadecimal values) in setting the MBE mode.
The MBE mode is set in hexadecimal values by dividing the 16 bits (b0 to b15) into 
the upper-half and lower-half 8 bits, or specifically by setting bit 0 in the lower-half 
8 bits to “1” or “0”.  Accordingly, since the upper-half 8 bits are always “00H”, set 
only the lower-half 8 bits (address 136H).
ADDRESS MBE MODE
136H  Lower-half 8 bits setting address (b0 to b7)
137H Upper-half 8 bits setting address (b8 to b15)
xi:
System parameter values See  below:
[1] System parameter values on setting the MBE mode for the addresses.
