71M6511/71M6511H Demo Board User’s Manual
2.5.3 RTC
Testing the RTC inside the 71M6511/6511H IC is straightforward and can be done using the serial command
line interface (CLI) of the Demo Code.
To set the RTC and check the time and date, we apply the following sequence of CLI commands:
>M10
>RTD05.09.27.3
>M9
>RTT10.45.00
LCD display to show calendar date
Sets the date to 9/27/2005 (Tuesday)
LCD display to show time of day
Sets the time to 10:45:00. AM/PM distinction: 1:22:33PM = 13:22:33
2.5.4 HARDWARE WATCHDOG TIMER
The hardware watchdog timer of the 71M6511/6511H is disabled when the voltage at the V1 pin is at 3.3V
(V3P3). On the Demo Boards, this is done by plugging in a jumper at TP10 between the V1 and V3P3 pins.
Programming the flash memory or emulation using the ADM51 In-Circuit-Emulator can
only be done when a jumper is plugged in at TP10 between V1 and V3P3.
Conversely, removing the jumper at TP10 will enable the hardware watchdog timer.
2.5.5 LCD
Various tests of the LCD interface can be performed with the Demo Board, using the serial command line
interface (CLI):
The display outputs are enabled by setting the LCD_EN register to 1.
Register Name
LCD_EN
Address [bits]
2021[5]
R/W
R/W
Description
Enables the LCD display. When disabled, VLC2, VLC1, and
VLC0 are ground as are the COM and SEG outputs.
To access the LCD_EN register, we apply the following CLI commands:
>RI21$
>25
>RI21=5
>RI21=25
Reads the hex value of register 0x2021
Response from Demo Code indicating the bit 5 is set
Writes the hex value 0x05 to register 0x2021 causing the display to be switched off
Sets the LCD_EN register back to normal
The 71M6511/6511H provides a charge pump capable of boosting the 3.3VDC supply voltage up to 5.0VDC.
The boost circuit is enabled with the LCD_BSTEN register. The 6511 Demo Boards have the boost circuit
enabled by default.
Register Name
LCD_BSTEN
Address [bits]
2020[7]

Description
Enables the LCD voltage boost circuit.
