Table 10-608 lists the memory-mapped registers for the UDMASS_INTA0_CFG_GCNTRTI. All register offset addresses not listed in Table 10-608 should be considered as reserved locations and the register contents should not be modified.
The Global Event Count Registers RTI region is accessed by setting the cfg_rsel signal to 6 during the access. The address map for this region is as follows:
Instance | Base Address |
---|---|
NAVSS0_UDMASS_INTA0_CFG_GCNTRTI | 3380 0000h |
MCU_NAVSS0_UDMASS_INTA0_GCNTRTI | 2A60 0000h |
Offset | Acronym | Register Name | NAVSS0_UDMASS_INTA0_CFG_GCNTRTI Physical Address | MCU_NAVSS0_UDMASS_INTA0_GCNTRTI Physical Address |
---|---|---|---|---|
0h + formula | UDMA_INTA_COUNT_j | ETL Count Register | 3380 0000h + formula | 2A60 0000h + formula |
UDMA_INTA_COUNT_j is shown in Figure 10-223 and described in Table 10-610.
Return to Summary Table.
The ETL Count register is read by software to determine how many times the event message has been received. This register can be written to decrement the count by a specified amount to acknowledge that a count has been processed by the host.
Offset = 0h + (j * 1000h); where
j = 0h to 1FFh for NAVSS0_UDMASS_INTA0_CFG_GCNTRTI
j = 0h to FFh for MCU_NAVSS0_UDMASS_INTA0_CFG_GCNTRTI
