NOTES:

1. R5 can either be directly connected to VDD, or connected to an input voltage

≥ VIH, or left unconnected.

2. L4 and U4 can be either NC or connected to VSS.

3. T7 can be left unconnected and the device will always remain in active mode.

4. DNU = Do not use; Pins U2, U3, U4, U5 and U6 are reserved for respective JTAG Pins: TMS, TDI, TCK, TDO and

TRST. Within the current version, these

pins are left unconnected.
