TDE,#0FE00H
C,#0F0H
A,#0H
[TDE+],A
;
;
;
Clear SADDR (internal high-speed RAM area)
Zero-clear from FE00H to FEEFH
FEF0H to FEFFH: register 0
;Set flag
;
CPU clock (such as 3.125-MHz clock)
;
This reserves three bytes of data for transmission to the
μ
PD75F4264
;
The setting range is 100 Hz to 99,999,900 Hz
;
The high-order one byte is used to calculate the wait time
MOVG
MOVG
WHL,#031250H
RUCLK,WHL
MOV
RUCKS,#0
;
;
;
;
Select clock (such as for the supplied clock)
When “0”: clock is supplied from flash writer
When “1”: clock from the
μ
PD75F4264 is used
(RUCKS can only be set to “0” via the
μ
PD75F4264)
MOVW
RUERT,#0200H
;
;
;
Erase time (a time of two seconds is used as an example)
This is the time required to erase the
μ
PD75F4264’s flash memory
Two bytes of data are reserved (in 10-ms units)
MOVG
MOVG
WHL,#000000H
RUSADR,WHL
;
;
;
;
Write start address (000000H is used as an example)
or read start address
* Although three bytes of data are reserved, two bytes of data is sufficient
if the write size is no more than 64 Kbytes
MOVG
MOVG
WHL,#000FFFH
RUEADR,WHL
;
;
;
Write end address (000FFFH is used as an example)
or read end address (up to 1FH for the
μ
PD75F4264)
* Although three bytes of data are reserved, two bytes of data is sufficient
if the write size is no more than 64 Kbytes
MOV
RURTYP,#0
;
;
Memory type selection for write
When “0”: flash memory, when “1”: EEPROM
MOVW
RUWTM,#0050H
;
;
;
Write time (50
μ
s is used as an example)
This value is stored as a decimal number (example: 50
μ
s = 0x0050)
* The write time for the
μ
PD75F4264 is fixed as 50
μ
s
MOV
RUSCK,#000AH
;
;
;
Communication clock (1 kHz is used as an example)
Two bytes of data are reserved (in 100-Hz units) for the clock used in
communications with the
μ
PD75F4264 The setting range is 100 Hz to 1 MHz
