is, bit 0 denotes GPIO 0, bit 1 denotes GPIO 1, etc. For example, to write
pins 0, 1, and 3, the pin numbers should be '0x0'.
–
Enter the value in the (R/W) result field from '0x01' to '0x0F' to write the value
of the output pin. The pin numbers are ordered bit-wise, that is, bit 0 denotes
GPIO 0, bit 1 denotes GPIO 1, etc. For example, to set pins 0 and 1 high and
pin 3 to low, the pin number should be '0x0B/. Key in the value '0x0A' to write.
–
Click the <write GPIO data> button to write the GPIO output pins.
SMBus
When the application is executed, click the radio button to test each access mode,
that is, access a byte, access multiple bytes and access a word. All data must be

multiple bytes" mode must be written in decimal. The functionalities of the watchdog
can be tested as follows:
Read a byte
–
Click the <Access a byte> radio button.
–
Enter the slave device address in the Slave address field.
–
Input the register offset in the Register Offset field.
–
Click the <read SMBus data> button to view a byte of data from the device in
the Result field.
Write a byte
–
Click the he <Access a byte> radio button.
–
Enter the slave device address in the Slave address field.
–
Input the register offset in Register Offset field.
–
Input the desired data in the Results field to write to the device.
–
Click the <write SMBus data> button to write data to the device through
SMBus.
Read a word
–
Click the <Access a word> radio button.
–
Enter the slave device address in the Slave address field.
