consecutive data memory addresses from the address indicated by the current contents of the data memory. As a
result, the data pointer contents are subtracted by 5 ( 5). Afterwards, the same operation is repeated, each time

code and is decoded to 5
subsequent five data memory addresses from the address indicated by the current contents of the data memory.
The data processing mode is set to the AND mode by this command. Afterwards, data processing will be
When this mode is set, the 8-bit data, written into the serial/parallel register by the CPU, is ANDed with the data
The data processing mode is set to the character mode with left entry by this command. Afterwards, data
When this mode is set, the 8-bit data written into the serial/parallel register by the CPU is treated as ASCII or JIS
The data processing mode is set to the character mode with right entry by this command. Afterwards, data
When this mode is set, the 8-bit data written into the serial/parallel register by the CPU is treated as ASCII or JIS
As a result, the data pointer contents are added by 5 (+5).
Afterwards, the same operation is repeated, each time an 8-bit data is written by the CPU.
