CTRLE – Control Register E
CTRLF – Control Register F
• Bit 3 – BLINKEN: Blink Enable
Writing this bit to one, the blink mode starts at the frequency specified by LCD blink rate (BLINK-
RATE). By writing it to zero, the LCD blink module stops. This BLINKEN bit takes effect at the
beginning of the next LCD frame. (For more details see
• Bit 2 – Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bits 1:0 – BLINKRATE[1:0]: LCD Blink Rate
The BLINKRATE bit-field defines the frequency of the hardware Display Blinking when the
BLINKEN bit is set. Blink frequencies are shown in
Table 24-10. Blink Frequencies
• Bits 7:4 – BPS1[3:0]: Blink Segment Selection 1
This bit-field defines the segment which is connected on SEG1 for blinking. Each bit of
BPS1[3:0] corresponds to one of the common terminals.
• Bits 3:0 – BPS0[3:0]: Blink Segment Selection 0
This bit-field defines the segment which is connected on SEG0 for blinking. Each bit of
BPS0[3:0] corresponds to one of the common terminals.

If no segment to blink is selected (BPS1[3:0] = BPS1[3:0] = 0) and if the BLINKEN bit is set, then
the full display is blinking.
