10.2.3.3 Icon_ctl
Table 25.
The PCF2119x can drive up to 160 icons. See
icon mapping.
Bit IM: When bit IM = 0, the chip is in character mode. In the character mode characters
and icons are driven (multiplex drive mode 1:18 or 1:9). The V
produces the V
When bit IM = 1, the chip is in icon mode. In the icon mode only the icons are driven
(multiplex drive mode 1:2). The V
programmed with register V
Table 26.
Bit IB: Icon blink control is independent of the cursor/character blink function.
When bit IB = 0, the icon blink is disabled. Icon data is stored in CGRAM character 0 to 3
(4 × 8 × 5 = 160 bits for 160 icons).
When bit 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).
Icon states for the even phase are stored in CGRAM characters 0 to 3
(4 × 8 × 5 = 160 bits for 160 icons). These bits also define icon state when icon blink is not
used (see
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 7 may be used as
normal CGRAM characters.
