This means that the device needs t
When activating TX it requires t
For timing information refer to Table 4-3.
For test purposes a TESTMODE is provided by the Sequencer as well. In this mode the BLOCK_PD
register be set to various values. This will override the Sequencer timing. Depending on the settings
in Config Register 00H the corresponding building blocks are enabled, as shown in the subsequent
figure.
