Command 0 is used to select the Command Bank. Bits
BS1 and BS0 are the two flags that indicate the current
Command Bank being executed. During a master reset
these two bits are cleared (BS1 = 0, BS0 = 0). Each
command has its own associated Command Bank, this is
shown in Table 8.

Command 1 is not used in the PCA8514.

This command writes character attribute data into the DCR
Attribute Register. The actual character attribute is
dependent upon the code selected by Command 5.
Sections 9.3.1 to 9.3.2 define the character attribute data
loaded by Command 2 when Command 5 selects either a
Character Font Code, a Carriage Return Code or a Space
code. See Tables 2, 3 and 4 for the three code formats.
