RECORD TYPE COMMAND/DATA FUNCTION
05 Miscellaneous Read Functions
General Format of Function 05
:02xxxx05ffsscc
Where:
02 = number of bytes (hex) in record
xxxx = required field, but value is a “don’t care”
05 = “Miscellaneous Read” function code
ffss = subfunction and selection code
0000 = read signature byte – manufacturer id (15H)
0001 = read signature byte – device id # 1 (C2H)
0002 = read signature byte – device id # 2
P89C60X2 = EFh
P89C61X2 = F0h
0003 = read FX2 bit
0080 = read ROM code revision
0700 = read security bits
0701 = read status byte
cc = checksum
Example 1:
:020000050001F8 read signature byte – device id # 1
Example 2:
:020000050003F6 read FX2 bit (bit 7 = 0 represents 12-clk mode, bit 7 = 1
represents 6-clk mode)
Example 3:
:02000005008079 read ROM code revision (0A: Rev. A; 0B: Rev. B, etc.)
06 Direct Load of Baud Rate
General Format of Function 06
:02xxxx06hhllcc
Where:
02 = number of bytes (hex) in record
xxxx = required field, but value is a “don’t care”
06 = ”Direct Load of Baud Rate” function code
hh = high byte of Timer 2
ll = low byte of Timer 2
cc = checksum
Example:
:02000006F500F3
