VM register
On reset, bit1-Bit4 are loaded to configurations that are selected by the user in PSDsoft
Express. bit0 and bit7 are always cleared on reset. bit0-Bit4 are active only when the device
is configured in Philips 80C51XA mode.
SR_code
0 = PSEN cannot access SRAM in 80C51XA modes.
1 = PSEN can access SRAM in 80C51XA modes.
Boot_code
0 = PSEN cannot access Secondary NVM in 80C51XA modes.
1 = PSEN can access Secondary NVM in 80C51XA modes.
FL_code
0 = PSEN cannot access primary Flash memory in 80C51XA modes.
1 = PSEN can access primary Flash memory in 80C51XA modes.
Boot_data
0 = RD cannot access Secondary NVM in 80C51XA modes.
1 = RD can access Secondary NVM in 80C51XA modes.
FL_data
0 = RD cannot access primary Flash memory in 80C51XA modes.
1 = RD can access primary Flash memory in 80C51XA modes.
Peripheral mode
0 = Peripheral mode of Port F is disabled.
1 = Peripheral mode of Port F is enabled.
