Programmers Model 3.3 GPR register descriptions This section describes the GPR registers. Table 3-1 on page 3-3 provides cross-references to individual registers. 3.3.1 Debug Power Request Register The CPWRUPREQ Register characteristics are: Purpose Controls the values of the cpwrupreq outputs from CXGPR. Each bit in this register controls the corresponding output on the cpwrupreq port. CXGPR contains hardware logic to ensure that the 4-phase handshake is not violated on the CPWRUP interfaces. If CXGPR asserts a powerup request that is not acknowledged, that is, cpwrupreq[n] = 1 and cpwrupack[n] = 0, writing a 0 to the CPWRUPREQ register bit[n] does not affect the cpwrupreq[n] output. Similarly, if CXGPR sends a powerdown request that is not acknowledged, that is, cpwrupreq[n] is 0 and cpwrupack[n] = 1, writing a 1 to the CPWRUPREQ register bit[n] does not affect the cpwrupreq[n] output. Usage constraints There are no usage constraints. Configurations This register is available in all configurations. Attributes See the register summary in Table 3-1 on page 3-3. Figure 3-1 on page 3-5 shows the bit assignments. ARM DDI 0480D Copyright © 2011, 2012 ARM. All rights reserved. 3-4 ID010213 Non-Confidential
