There's no general answer. Flash stores bits; all else being equal, those could be "data" bits or "program" bits. It's just a question of whether or not that particular memory is wired to respond to the 8051 core's instruction fetch cycle, or data read/write cycles. Either (or both...

process. Therefore only 56K byte OTP memory area is usable for 8051 microcontroller. Note 2: Total size of RAM is 8K byte including MCE program, MCE data, and 8051 data. Different sizes can be allocated depending on applications. IRM...
