TS80C52X2
8.3.3 Programming Algorithm
The Improved Quick Pulse algorithm is based on the Quick Pulse algorithm and decreases the number of pulses
applied during byte programming from 25 to 1.
To program the TS87C52X2 the following sequence must be exercised:
Repeat step 2 through 6 changing the address and data for the entire array or until the end of the object file is
reached (See Figure 12.).
8.3.4 Verify algorithm
Code array verify must be done after each byte or block of bytes is programmed. In either case, a complete verify
of the programmed array will ensure reliable programming of the TS87C52X2.
P 2.7 is used to enable data output.
To verify the TS87C52X2 code the following sequence must be exercised:
Repeat step 2 through 3 changing the address for the entire array verification (See Figure 12.)

* See Table 31. for proper value on these inputs
Step 1: Activate the combination of control signals.
Step 2: Input the valid address on the address lines.
Step 3: Input the appropriate data on the data lines.
Step 4: Raise EA/VPP from VCC to VPP (typical 12.75V).
Step 5: Pulse ALE/PROG once.
Step 6: Lower EA/VPP from VPP to VCC
Step 1: Activate the combination of program and control signals.
Step 2: Input the valid address on the address lines.
Step 3: Read data on the data lines.
