IECITOP1 is a read and write register. In integration test mode, it enables outputs to be both written to and read from.
Figure 4.5 shows the bit assignments for the register.
Table 4.6 lists the register bit assignments.
Table 4.6. IECITOP1 Register 1 bit assignments
| Bit | Name | Description |
|---|---|---|
| [31:4] | - | Reserved, read undefined, do not modify. |
| [3] | IECSYNCMODEREQ | Intra-chip output. Writes to this bit set the
value to be driven onto the IECSYNCMODEREQ output
in integration test mode. Reads return the value of IECSYNCMODEREQ at the output of the
test multiplexer. The reset value is 0. |
| [2] | IECPWRREQ | Intra-chip output. Writes to this bit set the
value to be driven onto the IECPWRREQ output
in integration test mode. Reads return the value of IECPWRREQ at the output of the test
multiplexer. The reset value is 0. |
| [1] | IECCPUSLPINT | Intra-chip output. Writes to this bit set the
value to be driven onto the IECCPUSLPINT output
in integration test mode. Reads return the value of IECCPUSLPINT at the output of the test
multiplexer. The reset value is 0. |
| [0] | IECCPUWUINT | Intra-chip output. Writes to this bit set the
value to be driven onto the IECCPUWUINT output
in integration test mode. Reads return the value of IECCPUWUINT at the output of the test
multiplexer. The reset value is 0. |
