180 / 324 page  VCore-Ie System and CPU Interfaces VMDS-10488 VSC7511 Datasheet Revision 4.2 165 register field is reserved. When writing reserved register fields, these must be set to 0 or 1, as indicated in the table. The SFR::GPR register is an 8-bit general-purpose register. The value of this register is available to external CPU through ICPU_CFG::MPU8051_STAT.MPU8051_GPR. The contents of the SFR::MPAGE register are used for the upper eight address bits during “MOVX A, @Ri” and “MOVX @Ri, A” instructions. For legacy 8051 designs, the MPAGE register replaces the Port- 2-Latch. To enable memory access instructions (“MOVX A, @Ri"“ and “MOVX @Ri, A”), SFR register 0x8E must be written to 0 (“MOV 0x8E, #0x00”). For more information about the SFR::MMAP register, see Mapping On-Chip Memory, page 167. For more information about the SFR::RA_* registers, see Accessing the VCore-Ie Shared Bus, page 167. 4.3.5 Starting the VCore-Ie CPU This section provides information about the startup procedures for the VCore-Ie CPU. The procedures apply to both manual and automatic booting. Table 131 • Special Function Registers (SFR) Register Addr Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 GPR1 1.
