7. Initialization is executed. The initialization program is downloaded together with the
8. The return value in the initialization program, the FPFR parameter is determined.
9. All interrupts and the use of a bus master other than the CPU are disabled during
10. FKEY must be set to H'5A and the user MAT must be prepared for programming.
11. The parameters required for programming are set. The start address of the programming
programming program to the on-chip RAM. The entry point of the initialization program is at
the address which is 32 bytes after #DLTOP (start address of the download destination
specified by FTDAR). Call the subroutine to execute initialization by using the following
steps.
MOV.L #DLTOP+32,ER2

⎯ The general registers other than ER0 and ER1 are held in the initialization program.
⎯ R0L is a return value of the FPFR parameter.
⎯ Since the stack area is used in the initialization program, a stack area of 128 bytes at the
⎯ Interrupts can be accepted during execution of the initialization program. Make sure the
programming/erasure. The specified voltage is applied for the specified time when
programming or erasing. If interrupts occur or the bus mastership is moved to other than the
CPU during programming/erasure, causing a voltage exceeding the specifications to be
applied, the flash memory may be damaged. Therefore, interrupts are disabled by setting bit 7
(I bit) in the condition code register (CCR) to B'1 in interrupt control mode 0 and by setting
bits 2 to 0 (I2 to I0 bits) in the extend register (EXR) to B'111 in interrupt control mode 2.
Accordingly, interrupts other than NMI are held and not executed. Configure the user system
so that NMI interrupts do not occur. The interrupts that are held must be executed after all
programming completes. When the bus mastership is moved to other than the CPU, such as to
the DMAC or DTC, the error protection state is entered. Therefore, make sure the DMAC does
not acquire the bus.
destination on the user MAT (FMPAR parameter) is set in general register ER1. The start
address of the program data storage area (FMPDR parameter) is set in general register ER0.
⎯ Example of FMPAR parameter setting: When an address other than one in the user MAT
maximum must be allocated in RAM.
program storage area and stack area in the on-chip RAM and register values are not
overwritten.
area is specified for the start address of the programming destination, even if the
programming program is executed, programming is not executed and an error is returned to
the FPFR parameter. Since the program data for one programming operation is 128 bytes,
the lower eight bits of the address must be H'00 or H'80 to be aligned with the 128-byte
boundary.
