Is it necessary to disable interrupts in user programs?

Latest Updated:02/26/2007

Question:

(Flash Memory)  There's a note stating "interrupts cannot be used in CPU rewrite mode". Is it necessary to disable interrupts in user programs? [2007/02/26]

Answer:

Interrupts are not automatically disabled in CPU rewrite mode. The user should execute the SEI instruction to disable interrupts (I = 1) before entering CPU rewrite mode (by setting the CPU rewrite mode selection bit to "1"). (#106585)
