7.2.2. Manual Reset

A manual reset of the SX1235 is possible even for applications in which VDD cannot be physically disconnected. Pin 6

should be pulled high for a hundred microseconds, and then released. The user should then wait for 5 ms before using the

chip.

Note

whilst pin 6 is driven high, an over current consumption of up to ten milliamps can be seen on VDD.
