Chapter 3 Software Configuration

3-8. WATCHDOG TIMER CONFIGURATION

The I/O port address of the watchdog timer is 2E(hex) and 2F(hex). 2E (hex) is the address port. 2F(hex) is the data port. User must first assign the address of register by writing address value into address port 2E(hex), then write/read data to/from the assigned register through data port 2F (hex).

Configuration Sequence

There are three steps to completing the configuration setup:

(1)Enter the MB PnP Mode.

(2)Modify the data of configuration registers.

(3)Exit the MB PnP Mode.

Undesired result may occur if the MB PnP Mode is not exited normally.

(1) Enter the MB PnP Mode

To enter the MB PnP Mode, four special I/O write operations are to be performed.

(2) Modify the data of configuration registers

All configuration registers can be accessed after entering the MB PnP Mode. Before accessing a selected register, the content of index 07h must be changed to the LDN to which the register belongs, except some Global registers.

(3) Exit the MB PnP Mode

Set bit 1 of the configure control register (index=02h) to “1” to exit the MB PnP Mode.

Sample code: ;***********************************************; ;Enter PnP Mode ;***********************************************; MOVDX,2Eh

MOVAL,87h

OUTDX,AL

MOVAL,01h

MOVAL,55h

OUTDX,AL
