The EOF flag can only be cleared by writing a 1. Writing a 0 has no effect. If enabled (LCDINT = 1), EOF
causes an interrupt request. The number of frames (NOF) bits determine how many frames are count until
EOF flag is set. The possible number of frames are:
NOF= 0x00: An interrupt is requested at the end of every frame.
NOF= 0x01: An interrupt is requested at the end of every second frame.
NOF= 0x02: An interrupt is requested at the end of every third frame.
...
NOF= 0xFF: An interrupt is requested at the end of every 256th frame.
22.6 LCD Waveform Examples
The following figures show the timing examples of the LCD output waveforms for the available modes of
operation. The contrast control is disabled in all examples (CCEN = 0 in LCDCCR). Selected reference
voltage is VLCD, but could also be VDDX.
22.6.1 1/1 Duty Multiplexed with 1/1 Bias Mode
Duty = 1/1:DUTY = 000
Bias = 1/1:BIAS = 0 or BIAS = 1
V₀ = V₁ = VSSX V₂ = V₃ = VLCD
- Only BP0 is used, a maximum of 64 segments are displayed.
