Option Bits in this space are altered to change the chip configuration at reset
Reserved
These option bits are reserved for future use and must always be 1. This setting is the
default for unprogrammed (erased) Flash.
Option bits in this space are altered to change the chip configuration at reset.
ROMLESS 16—ROMLESS 16 select
0 = If the device is ROMLESS, the data bus is 8 bits wide and is on Port E[7:0].
1 = If the device is ROMLESS, the data bus is 16 bits wide and is on
{Port J[7:0], Port E[7:0]}
LPOPT—Low power option
0 = The part will come up in low power mode. The Clock is divide by 8 and the flash will
only be accessed the last half of the last cycle of the divide. This reduces Flash power
consumption.
1 = The part will come up normally.
