How to Use the Routines
On-Chip FLASH Programming Routines, Rev. 4
Freescale Semiconductor

Example 6:
Programming a Range Smaller than a Row
PRGRNGE can be used to program a range less than 32 bytes. Example 6 shows how to program $55
and $AA at location $E004 and $E005, respectively.
PRGRNGE equ $038A ;LB8 PRGRNGE jump address
mov #$55,DATA
mov #$AA,DATA+1
mov #$18,CPUSPD ;fop = 6.0MHz in this example
ldhx #$E005 ;Load last address to LADDR
sthx LADDR
ldhx #$E004 ;Load beginning address to H:X
jsr PRGRNGE ;Call PRGRNGE routine
ERARNGE
ERARNGE can be called to erase a page (64 bytes) or a whole array of FLASH. Registers H and X can
be any address within the page or array to be erased. To select erase size, CTRLBYT is used. Writing
$40 to CTRLBYT selects the entire array (MASS) erase. Writing $00 to CTRLBYT selects the page erase.
When other values are written to CTRLBYT, the erase operation is not executed. This routine supports
an internal operating frequency between 1.0 MHz and 8.4 MHz.
In this routine, both PAGE erase time (t
Erase
) and MASS erase time (t
MErase
) are set between 4 ms and
5.5 ms. The CPUSPD value is the nearest integer of f
op
(in MHz) times 4. For example if f
op
is 3.1 MHz,
the CPUSPD is 12 ($0C). If f
op
is 4.9152 MHz, the CPUSPD is 20 ($14).
Interrupts are masked and the COP is serviced in ERARNGE. The first COP is serviced on
(40+3xCPUSPD) bus cycles after this routine is called in the user software.
Entry Condition
CTRLBYT — For MASS erase, write $40. For PAGE erase, write $00.
H:X — Contains an address within a desired erase page or an array.
CPUSPD — Contains the nearest integer value of f
op
(in MHz) times 4.
Exit Condition
None
