Telemetry
Figure 72 Switching frequency telemetry block diagram
8.10 General-purpose ADC telemetry
The general-purpose TSADC outputs are low-pass filtered as illustrated in the block diagram in Figure 73 . The
IMON and XADDR BWs are programmed via registers tlm_kfp_imon and tlm_kfp_xaddr according to the
following definition:
•
tlm_kfp_xaddr follows the BW programming given in Table 55
•
For ts_muxmode = 5, 7; tlm_kfp_imon follows the BW programming given in Table 55
•
For ts_muxmode = 4, 6; tlm_kfp_imon follows the BW programming given in Table 57
The tlm_kfp_imon BW programming depends on the ts_muxmode selection due to the different sample rates.
Figure 73 General-purpose ADC telemetry block diagram
The PRISEN BW is programmed through register tlm_kfp_prisen and follows a slightly different BW
programming table, since it is sampled twice in the TSADC sampling cycle. The PRISEN BW programming is
defined in
Table 57 for ts_muxmode = 5, 7 and in Table 58 for ts_muxmode = 4, 5.
