The ITATBDATA0 Register characteristics are:
The Integration Test ATB Data 0 Register performs different functions depending on whether the access is a read or a write:
a write outputs data to the byte boundaries of ATDATAM
a read returns the data from ATDATASn,
Where n is the index of the slave port that is enabled. For details
about ports that are enabled, see Funnel Control Register. The read data is only valid when ATVALIDSn is
HIGH.
There are no usage constraints.
This register is available in all configurations.
See the register summary in Table 3.35.
Figure 3.35 shows the bit assignments.
Table 3.38 shows the bit assignments.
