5.4.1.5. Low voltage reset(LVR)

The GPES282A provides Low Voltage Reset (LVR) function that

will reset all functions into the initial state if the VDD power drops

below 2.1V for longer than two T7 clock cycles(T7=CPU CLK*128).

As a result, it prevents the GPES282A entering into a malfunction

state.

The LVR function is the same as Power ON Reset.

For

The Low Voltage Reset can be enabled or disabled in a program.

This option must be defined in definition area.

LVR_ENABLE; enable

LVR_DISABLE; disable

5.4.1.6. Infrared Red (IR) function

Some IR parameters must be defined in Definition Area before

using IR function.

We will only introduce the commands here.

For more details on how to use these commands in your program,

please refer to GPES II Programming Guide.

5.4.2. Entry point (Label)

The essence applied in GPES II is the ENTRY POINT.

Each

trigger pin is assigned an entry point.

Instructions must be

located in a new line under its entry point.

Any instruction located

with the same line as entry point will cause error when compiling.

Users can also define a label (ID) for an entry point.

A label can

be the combinations of number and character, but not underscore.

In addition, a label can not start with a number.

Example

SpeechLoop:

Sound1+Sound2

JP

SpeechLoop

When a pin is triggered, the program jumps to its corresponding

entry point and starts executing.

The entry points are fixed

values.

For instance, ‘0’ is the entry point of TG1 when 1

0.

‘1’

is the entry point of TG2 when 1

0.

Users can either use Entry

Point ID or Entry Point Abbreviator to express an entry point.

A

summary of entry point for each trigger pin is as follows:
