NOTES:

1. Active Mode:

a. The following pins must be forced to VDD: EA, RST, Port 0, and EW.

b. The following pins must be forced to VSS: STADC, AVss, and AVref–.

c. Ports 1.6 and 1.7 should be connected to VDD through resistors of sufficiently high value such that the sink current into these pins cannot

exceed the IOL1 spec of these pins.

d. The following pins must be disconnected: XTAL2 and all pins not specified above.

2. Idle Mode:

a. The following pins must be forced to VDD: Port 0 and EW.

b. The following pins must be forced to VSS: RST, STADC, AVss,, AVref–, and EA.

c. Ports 1.6 and 1.7 should be connected to VDD through resistors of sufficiently high value such that the sink current into these pins cannot

exceed the IOL1 spec of these pins. These pins must not have logic 0 written to them prior to this measurement.

d. The following pins must be disconnected: XTAL2 and all pins not specified above.

3. Power Down Mode:

a. The following pins must be forced to VDD: Port 0 and EW.

b. The following pins must be forced to VSS: RST, STADC, XTAL1, AVss,, AVref–, and EA.

c. Ports 1.6 and 1.7 should be connected to VDD through resistors of sufficiently high value such that the sink current into these pins cannot

exceed the IOL1 spec of these pins. These pins must not have logic 0 written to them prior to this measurement.

d. The following pins must be disconnected: XTAL2 and all pins not specified above.

Purchase of Philips I2C components conveys a license under the Philips’ I2C patent

to use the components in the I2C system provided the system conforms to the

I2C specifications defined by Philips. This specification can be ordered using the

code 9398 393 40011.
