LCDCRB – LCD Control and Status Register B
• Bit 0 – LCDBL: LCD Blanking
When this bit is written to one, the display will be blanked after completion of a frame. All seg-
ment and common pins will be driven to ground.
• Bit 7 – LCDCS: LCD Clock Select
When this bit is written to zero, the system clock is used. When this bit is written to one, the
external asynchronous clock source is used. The asynchronous clock source is either
Timer/Counter Oscillator or external clock, depending on EXCLK in ASSR. See
operation of the Timer/Counter” on page 150
• Bit 6 – LCD2B: LCD 1/2 Bias Select
When this bit is written to zero, 1/3 bias is used. When this bit is written to one, ½ bias is used.
Refer to the LCD Manufacture for recommended bias selection.
• Bit 5:4 – LCDMUX1:0: LCD Mux Select
The LCDMUX1:0 bits determine the duty cycle. Common pins that are not used are ordinary port
pins. The different duty selections are shown in
Table 23-2.
Note:
• Bit 3 – Res: Reserved Bit
This bit is reserved and will always read as zero.
• Bits 2:0 – LCDPM2:0: LCD Port Mask
The LCDPM2:0 bits determine the number of port pins to be used as segment drivers. The dif-
ferent selections are shown in
Table 23-3.
