BLINK MODE
Blink mode is enabled by setting the BLINKEN bit (Bit 5) in the
LCD configuration SFR (LCDCON, Address 0x95). This mode
is used to alternate between the LCD on state and LCD off state
so that the LCD screen appears to blink. There are two blink
modes: a software controlled blink mode and an automatic
blink mode.
Software Controlled Blink Mode
The LCD blink rate can be controlled by user code by toggling
the BLKMOD bits (Bits[7:6]) in the LCD clock SFR (LCDCLK,
Address 0x96) to turn the display on and off at a rate that is
determined by the MCU code.
Automatic Blink Mode
There are five blink rates. These blink rates are selected by the
BLKMOD bits (Bits[7:6]) and the BLKFREQ bits (Bits[5:4]) in
the LCD clock SFR (LCDCLK, Address 0x96); see Table 95.
SCROLLING MODE
The ADE5166/ADE5169/ADE5566/ADE5569 can store up to
four screens in memory. The LCD driver can use any of these
screens by setting the SCREEN_SEL bits (Bits[3:2]) in the LCD
Configuration Y SFR (LCDCONY, Address 0xB1) and clearing
the refresh bit (Bit 0) in the same register. The software scrolling
of the screens can then be achieved by a one-command instruction.
Data Sheet
Automatic Scrolling Mode
The ADE5166/ADE5169/ADE5566/ADE5569 provide automatic
scrolling between the screens using the five available blink rates.
Setting the AUTOSCREENSCROLL bit (Bit 7) in the LCD Con-
figuration Y SFR (LCDCONY, Address 0xB1), as well as the
BLINKEN bit (Bit 5) in the LCD configuration SFR (LCDCON,
Address 0x95) enables this mode. To allow the scrolling frequency
to be selected, the BLKMOD bits (Bits[7:6]) in the LCD clock
SFR (LCDCLK, Address 0x96) should both be set to 1. The scrol-
ling rates are then selected by the BLKFREQ bits (Bits[5:4]) in
the LCD clock SFR (LCDCLK, Address 0x96); see Table 95.
Automatic scrolling mode is available in all operating modes.
DISPLAY ELEMENT CONTROL
Four banks of 15 bytes of data memory located in the LCD module
control the on or off state of each segment of the LCD. The LCD
data memory is stored in Address 0 through Address 14 in the
LCD module, with two extra bits defining which one of the four
screens is being addressed.
Each byte configures the on and off states of two segment lines.
The LSBs store the state of the even numbered segment lines,
and the MSBs store the state of the odd numbered segment lines.
For example, LCD Data Address 0 refers to segment Line 1 and
Line 0 (see Table 102). Note that the LCD data memory is
maintained in the PSM2 operating mode.
The LCD data memory is accessed indirectly through the LCD
pointer SFR (LCDPTR, Address 0xAC) and LCD data SFR
(LCDDAT, Address 0xAE). Moving a value to the LCDPTR SFR
selects the LCD screen and data byte to be accessed and initiates
a read or write operation (see Table 99).
