The PCF2119x can drive up to 160 icons. See Fig.19 for
CGRAM to icon mapping.

When IM = 0, the chip is in character mode. In the
character mode characters and icons are driven
(MUX 1 : 18). The V

When IM = 1, the chip is in icon mode. In the icon mode
only the icons are driven (MUX 1 : 2) and the V
generator, if used, produces the V

9.4
Icon blink control is independent of the cursor/character
blink function.
When IB = 0, icon blink is disabled. Icon data is stored in
CGRAM character 0 to 3 (4
160 icons).
When IB = 1, 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).
Icon states for the even phase are stored in CGRAM
characters 0 to 3 (4
These bits also define the icon state when icon blink is not
used.
Icon states for the odd phase are stored in CGRAM
character 4 to 7 (another 160 bits for the 160 icons). When
icon blink is disabled CGRAM characters 4 to 6 may be
used as normal CGRAM characters.
