37 / 100 page  37/100 PSD4256G6V This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. PAGE REGISTER The 8-bit Page Register increases the addressing capability of the MCU by a factor of up to 256. The contents of the register can also be read by the MCU. The outputs of the Page Register (PGR0- PGR7) are inputs to the DPLD decoder and can be included in the Sector Select (FS0-FS15, CSBOOT0-CSBOOT3), and SRAM Select (RS0) equations. If memory paging is not needed, or if not all eight page register bits are needed for memory paging, these bits may be used in the CPLD for general logic. See Application Note AN1154. Table 22, page 22 and Figure 11 show the Page Register. The eight flip-flops in the register are connected to the internal data bus (D0-D7). The MCU can write to or read from the Page Register. The Page Register can be accessed at address lo- cation CSIOP + E0h. Figure 11. Page Register MEMORY ID REGISTERS The 8-bit “Read only” Memory Status Registers are included in the CSIOP space. The user can determine the memory configuration of the PSD device by reading the Memory ID0 and Memory ID1 registers. The content of the registers is de- fined as shown in Table 26, page 24 and Table 27, page 24.
