DEVELOPING ST92F250 APPLICATIONS USING THE ST92F150-EMU2 EMULATOR
1.4 NEW P30, P66 AND P67 STANDARD I/O
As the ST92F250 does not include the J1850(JBLD) and the second CAN peripheral, it has
three additional standard Input/Output ports:
– The P3.0, replacing the VPWO pin and providing a complete 8-pin P3 port.
– The P6.6 and the P6.7, replacing the CAN1 RX and TX lines and providing a complete 8-pin
1.5 FLASH
1.5.1 FLASH Memory Mapping
To extend the FLASH memory size up to 256Kbytes, two 64Kbyte sectors have been added
in the ST92F250. These sectors F4 and F5 are mapped in the second and third memory seg-
ments.
1.5.2 FLASH & E3
The meaning of the four first bits of the FESR0 register (located at the addresses 224002h and
221002h) is modified to indicate the status of all the FLASH sectors.
Bit 6:0 = FESS[6:0]. Flash and E3
These bits are set by hardware and give the status of the 7 Flash and E3
For ST92F150 128K and 64K Flash devices:
– FESS3:0 = Flash sectors (F3:0)
For the ST92F250 256K Flash device:
– FESS3 gives the status of F5, F4 and F3 sectors: the combined status of all these three sec-
– FESS2:0 = Flash sectors (F2:0)
1.5.3 NON VOLATILE WRITE PROTECTION REGISTER (NVWPR)
The meaning of bit 3 of the NVWPR register (located at the address 231FFDh) is modified to
take the F4 and F5 sectors into account.
Bit 3 = WPRS3: FLASH Sectors 5-3 Write Protection.
This bit, if programmed to 0, disables any write access to Flash sectors F3, F4, and F5.
