When the device enters Low Power mode, an additional sleep time is inserted after
each burst, instead of once after every complete burst cycle. As a result, if only one
burst is required, the sleep duration during Low Power mode is doubled. And if two
bursts are required, the sleep duration is tripled.
In Standalone mode, the 100ms sleep duration low power becomes either a 200ms or
300ms sleep duration depending on the number of bursts required.
In I2C mode, it is required to program a sleep duration for one half or a third of the
desired sleep duration depending on the number of bursts required.
GET_PROTOCOL_VERSION returns 0x01 as I2CSpeed byte when it should return
0x00 (maximum speed is 100 kHz).
If a command is sent with an incorrect parity bit, the device reports an unsupported
command instead of a parity error.
In I2C mode, it is recommended to set the fast positive recalibration threshold to 5
using the SET_SCKEY_PARAMETERS command in order to ensure a reliable
behavior on low sensitivity keys.
AKS should be always enabled in BCD mode. The AKS pull-up option resistor should
be connected to pin KOUT2.
