the shifting operation is performed on internal registers that are not accessible in SW (when reading
LCD_AREGA and LCD_AREGB, the data that was original written will also be read back). The SW must
utilize the knowledge about the current state (ASTATE) to calculate what is currently output. ASTATE is
cleared when LCD_AREGA or LCD_AREGB are updated with new values. See Table 29.14 (p. 430)
for an example.
Table 29.14. LCD Animation Example
In the table, AREGASC = 10, AREGBSC = 10, ALOGSEL = 1 and the resulting data is be displayed on
segment lines 7-0 multiplexed with LCD_COM0.
