Specifications
3.6 Embedded Trace Macrocell
All registers in the ETM9 are programmed through a JTAG interface. The interface is an extension of the
ARM920T processor’s TAP controller, and is assigned scan chain 6. The scan chain consists of a 40-bit shift
register comprised of the following:
32-bit data field
7-bit address field
A read/write bit
The data to be written is scanned into the 32-bit data field, the address of the register into the 7-bit address field,
and a 1 into the read/write bit.
A register is read by scanning its address into the address field and a 0 into the read/write bit. The 32-bit data field
is ignored. A read or a write takes place when the TAP controller enters the UPDATE-DR state. The timing
diagram for the ETM9 is shown in Figure 2. See Table 10 on page 18 for the ETM9 timing parameters used in
Figure 2.
