Figure 8-7.
The following procedure is used to read the User space and is summarized in Figure 8-8:
The following procedure is used to read the Extra Row space and is summarized in Figure 8-8:
• Map the User space by writing 00h in FCON register.
• Read one byte in Accumulator by executing MOVC A, @A+DPTR with A = 0 & DPTR =
• Map the Extra Row space by writing 02h in FCON register.
• Read one byte in Accumulator by executing MOVC A, @A+DPTR with A = 0 & DPTR =
0000h to FFFFh.
FF80h to FFFFh.
