12 BSTAO. LCD Boost always on
If set, the selected by BST and enabled by BSTEN boost current is always on and not only during the time
frame generated by the state machine.
0 The Boost always on feature is disabled.
1 The Boost always on feature is enabled.
13 LCDOCS. LCD OSC Clock Select.
Can be written only when LCDEN is cleared. See Device Level information which OSC clock is defined as
first and second OSC clock.
0 First OSC clock is selected as clock for LCD Driver system (prescaler input) if LCDRCS is set.
1 Second OSC clock is selected as clock for LCD Driver system (prescaler input) if LCDRCS is set.
14 LCDINT. LCD interrupt enable.
0 Interrupt request is disabled.
1 Interrupt will be requested whenever EOF is set.
15 EOF. End of frame interrupt flag.
End of frame interrupt flag bit is set every time when NOF frames have been executed while LCDEN is set.
This flag can only be cleared by writing a 1. Writing a 0 has no effect. If enabled (LCDINT = 1), EOF
causes an interrupt request.
0 Defined via NOF bits frames have not been executed yet.
1 Defined via NOF bits frames have been executed.
16:23 NOF: Number of frames.
The number of frames bits determine how many frames are counted until an interrupt will be requested.
The possible number of frames are:
0x00 An interrupt is requested at the end of every frame.
0x01 An interrupt is requested at the end of every second frame.
.
.
0xFF An interrupt is requested at the end of every 256th frame.
26 LCDBPA: Backplane Adding
If set, the backplanes, which are not available in standard configuration, will be mapped on frontplanes as
shown in
Ta ble 22-28. Hence, up to six backplanes can be used to drive LCD displays.
0 No additional backplanes will be mapped on frontplanes.
1 Additional backplanes will be mapped on frontplanes.
29:31 LCDBPS: Backplane Shifting
Using these bits, backplanes will be swapped with frontplanes as shown in Table 22-28.
