The ITATBCTR0 characteristics are:
Performs different functions depending on whether the access is a read or a write:
A read returns the value of the atvalidsn
, atbytessn
,
and afreadysn
signals,
where the value of the Control Register at 0x000
defines n.
A write sets the value of the atvalidm, atbytesm, and afreadym signals.
There are no usage constraints.
This register is available in all configurations.
See the register summary in Table 3.33.
Figure 3.34 shows the bit assignments.
Table 3.39 shows the bit assignments.
