BSYAEIE Bit (Flash Access Error Interrupt Enable Bit)
RDYSTIE Bit (Flash Ready Status Interrupt Enable Bit)
This bit enables a flash access error interrupt to be generated if the flash memory during rewriting is accessed.
To change the BSYAEIE bit from 0 (flash access error interrupt disabled) to 1 (flash access error interrupt
enabled), make the setting as follows:
(1) Read the BSYAEI bit in the FST register (dummy read).
(2) Write 0 (no flash access error interrupt) to the BSYAEI bit.
(3) Set the BSYAEIE bit to 1 (flash access error interrupt enabled).
This bit enables a flash ready status error interrupt to be generated when the status of the flash memory
sequence changes from the busy to ready status.
To change the RDYSTIE bit from 0 (flash ready status interrupt disabled) to 1 (flash ready status interrupt
enabled), make the setting as follows:
(1) Read the RDYSTI bit in the FST register (dummy read).
(2) Write 0 (no flash ready status interrupt) to the RDYSTI bit.
(3) Set the RDYSTIE bit to 1 (flash ready status interrupt enabled).
