MTV012E
SLVADR (w) : Slave IIC address to which the slave block should respond.
4.0 Test Mode Condition
In normal application, users should not allow MTV012E to enter its test/program mode, outlined as
follows:
Test Mode A: RESET=1 & DA9=1 & DA8=0 & STO=0
Test Mode B: RESET falling edge & DA9=1 & DA8=0 & STO=1
Program Mode: RESET=1 & DA9=0 & DA8=1
5.0 INTERNAL EPROM
To program the internal EPROM, MTV012E must be running at a 4 to 6 MHz cycle time. The address of
an EPROM location to be programmed is applied to Port1 (A0 - A7) and pins P2.0 - P2.4(A8 - A12) of
Port2, while the code byte to be programmed is applied to DA0 - DA7. All other pins should be held at the
level indicated in the following table. The overall programming characteristics are very similar to those of
87C52 with the exception that pin #30 and pin #31 are switched.
