71M6543F/71M6543G Data Sheet
Transitions from both LCD and SLP mode to BRN mode can be initiated by the following events:
?
?
?
?
Wake-up timer timeout.
Pushbutton (PB) is activated.
A rising edge on SEGDIO4, or a high logic level on SEGDIO52 or SEGDIO55.
Activity on the RX or OPT_RX pins.
The MPU has access to a variety of registers that signal the event that caused the wake up. See 3.4
Wake-Up Behavior for details.
Table 61 shows the circuit functions available in each operating mode.

“--“ indicates that the corresponding circuit is not active
“Boost” implies that the LCD boost circuit is active (i.e., LCD_VMODE[1:0] = 10 ( I/O RAM 0x2401[7:6] )). The LCD boost
circuit requires a clock from the PLL to function. Thus, the PLL is automatically kept active if LCD boost is active while in
LCD mode, otherwise the PLL is de-activated.
