P89V660/662/664
80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI
6.4 I2C-bus interface
The I2C-bus uses two wires, Serial Clock (SCL) and Serial Data (SDA) to transfer
information between devices connected to the bus, and has the following features:
Bidirectional data transfer between masters and slaves
Erase Status bit and Boot vector
Input parameters:
R1 = 04H or 84H (WDT feed)
DPL = don’t care
DPH = don’t care
Return parameter(s):
ACC = 00 = pass
ACC = !00 = fail
Program Security bits
Input parameters:
R1 = 05H or 85H (WDT feed)
DPL = 00H = security bit 1
DPL = 01H = security bit 2
DPL = 02H = security bit 3
Return parameter(s):
ACC = 00 = pass
ACC = !00 = fail
Program Status bit, Boot vector,
6x/12x bit
Input parameters:
R1 = 06H or 86H (WDT feed)
DPL = 00H = program Status bit
DPL = 01H = program Boot vector
DPL = 02H = 6x/12x bit
ACC = Boot vector value to program
Return parameter(s):
ACC = 00 = pass
ACC = !00 = fail
Read Security bits, Status bit, Boot
vector
Input parameters:
ACC = 07H or 87H (WDT feed)
DPL = 00H = security bits
