Philips Semiconductors Preliminary data XA-G39 XA 16-bit microcontroller family 32K Flash/1K RAM, watchdog, 2 UARTs 2002 Mar 13 15 RECORD TYPE COMMAND/DATA FUNCTION 84 Display Device Data or Blank Check – Record type 84 causes the contents of the entire FLASH array to be sent out the serial port in a formatted display. This display consists of an address and the contents of 16 bytes starting with that address. No display of the device contents will occur if security bit 2 has been programmed. The dumping of the device data to the serial port is terminated by the reception of any character. General Format of Function 84 :05xxxx84sssseeeeffcc Where: 05 = number of bytes (hex) in record xxxx = required field, but value is a “don’t care” 84 = “Display Device Data or Blank Check” function code ssss = starting address eeee = ending address ff = subfunction 00 = display data 01 = blank check cc = checksum Example: :0500008440004FFF00E9 display 4000–4FFF 85 Miscellaneous Read Functions General Format of Function 85 :02xxxx85ffsscc Where: 02 = number of bytes (hex) in record xxxx = required field, but value is a “don’t care” 85 = “Miscellaneous Read” function code ffss = subfunction and selection code 0000 = read signature byte – manufacturer id (15H) 0001 = read signature byte – device id # 1 (EAH) 0002 = read signature byte – device id # 2 (XA–G39 = 65H)) 0700 = read security bits (returned value bits 3:1 = sb3,sb2,sb1) 0701 = read status byte 0702 = read boot vector cc = checksum Example: :02000085000178 read signature byte – device id # 1 |
