3.9.17.1 SSMCR – SSM
Control Register
Several options can be
selected in the control register for how the chip is initialized by the state
machines.| Name: | SSMCR |
| Offset: | 0x0E2 |
| Reset: | 0x00 |
| Bit | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | |
| | SETRPB | SETRPA | SSMTAE | SSMPVE | SSMTPE | SSMTGE | SSMTM | SSMTX | |
| Access | R/W | R/W | R/W | R/W | R/W | R/W | R/W | R/W | |
| Reset | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
Bit 7 – SETRPB Sequencer State
Machine Enable Transparent Path B
If this bit is set,
the transparent receive path B output is automatically enabled and disabled by the
sequencer state machine.
Bit 6 – SETRPA Sequencer State Machine Enable Transparent Path
A
If this bit is set, the
transparent receive path A output is automatically enabled and disabled by the
sequencer state machine.
Bit 5 – SSMTAE Sequencer State
Machine TX Ask-Shaping Enable
If this bit is set to
‘1’, the ask-shaping filter in the TX DSP is enabled during the
initialization via TX DSP enable.
Bit 4 – SSMPVE Sequencer State Machine PV Enable
This bit must be set to
‘1’ if the PA voltage regulator needs to be switched on for TX
initialization (5V application).
Bit 3 – SSMTPE Sequencer State
Machine TX Preemphasis Enable
If this bit is set to
‘1’, the preemphasis filter in the TX DSP is enabled during the
initialization via TX DSP enable.
Bit 2 – SSMTGE Sequencer State
Machine TX Gauss Enable
If this bit is set to
‘1’, the Gauss filter in the TX DSP is enabled during the
initialization via TX DSP enable.
Bit 1 – SSMTM Sequencer State Machine Temperature
Measurement
This bit configures the
start-up mode for temperature measurement. When this bit is set, SSMTX is ignored
and the start-up is done appropriately for temperature
measurement.
Bit 0 – SSMTX Sequencer State
Machine TX
This bit selects whether
initialization is done for transmission or for reception. If this bit is set to
‘1’, TX is selected. This influences the enabling of LNA or ADC
block in the RF front end, for example.
