16.2.3 Driving method for LCD driver
16.2.3.1 When using the booster circuit (LCDCR<BRES>="1")
external resistor divider. This selection is made in LCDCR<BRES>.
In the TMP86FS28DFG, LCD driving voltages can be generated using either an internal booster circuit or an
twofold (V2) or threefold (V3) to generate the output voltages for segment/common signals. When the
reference voltage is connected to the V2 pin, it is reduced to 1/2 (V1) or boosted to 3/2 (V3). When the
reference voltage is connected to the V3 pin, it is reduced to 1/3 (V1) or 2/3 (V2).
ing frequency, the higher the segment/common drive capability, but power consumption is increased.
Conversely, the slower the boosting frequency, the lower the segment/common drive capability, but power
consumption is reduced. If the drive capability is insufficient, the LCD may not be displayed clearly.
Therefore, select an optimum boosting frequency for the LCD panel to be used.
When the reference voltage is connected to the V1 pin, the booster circuit boosts the reference voltage
Note: When used as the booster circuit, bias should be composed to 1/3. Therefore, do not set
Table 16-3 shows the V3 pin current capacity and boosting frequency.
LCDCR<VFSEL> is used to select the reference frequency in the booster circuit. The faster the boost-
