Notes

6.Tested initially and after any design or process changes that may affect these parameters.

7.Full device operation requires linear VCC ramp from VDR to VCC(min) > 100 μs or stable at VCC(min) > 100 μs.

8.BHE.BLE is the AND of both BHE and BLE. Deselect the chip by either disabling chip enable signals or by disabling both BHE and BLE.
