Customization Commands

Table 9. Customization Opcodes.

The WTS701 has the ability for the

user to customize the way in which

it responds to certain text strings.

This is done by way of an

abbreviation

table.

The

customization opcodes allow the

user to interrogate and modify the

abbreviation table.

7.4.1 Command Description

The following section list all the standard commands that can be executed on the WTS701.

PWDN Go to POWER DOWN Mode

This command puts the WTS701 processor in power-down mode. This is a single word command

therefore no data is required for this command. The Power Down command places the WTS701

device into its lowest power consumption mode. In POWER DOWN mode, the device will only

respond to a Power Up command (PWUP) and Read Status (RDST) command. As soon as Power

Down sequence has ended, the RDY flag in the status word is cleared.

Description:

Put the WTS701 processor in power-down mode.

PWUP Power Up

This command wakes up the WTS701 processor to IDLE state. The result of this command is that the

WTS701 starts the power up sequence, which leads to bringing up internal supplies, resetting the

processor, all configuration registers are initialized to their default values and entering IDLE state. As

soon as power up sequence has ended, the RDY flag in the status word is asserted. The SCLC

command must be sent BEFORE PWUP.
