10.3 Bit IM
When IM = 0, the chip is in Character mode. In Character mode, characters and icons are
driven (MUX 1:18 or MUX 1:9). The VLCD generator, if used, produces the VLCD voltage
programmed in register VA.
When IM = 1, the chip is in Icon mode. In Icon mode only the icons are driven (MUX 1:2)
and the VLCD generator, if used, produces the VLCD voltage as programmed in register VB.
10.4 Bit IB
Icon blink control is independent of the cursor/character blink function.
When IB = 0, the icon blink is disabled. Icon data is stored in CGRAM characters 0 to 2
(3
× 8 × 5 = 120 bits for 120 icons).
When IB = 1, the icon blink is enabled. In this case each icon is controlled by two bits.
Blink consists of two half phases (corresponding to the cursor on and off phases called
even and odd phases hereafter).
CGRAM data bit = logic 1 turns the icon on, data bit = logic 0 turns the icon off.
Data in character codes 0 to 3 define the icon state when icon blink is disabled or during the even phase when icon blink is
enabled.
Data in character codes 4 to 7 define the icon state during the odd phase when icon blink is enabled (not used for icons when
icon blink is disabled).
