Programming Algorithm
Verify algorithm
Figure 17-1. Set-Up Modes Configuration
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 TS80C54/58X2 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 17-2.).
Code array verify must be done after each byte or block of bytes is programmed. In either case,
a complete verify of th e p rog ra mmed array will ensure reliable programming of the
TS87C54/58X2.
P 2.7 is used to enable data output.
To verify the TS87C54/58X2 code the following sequence must be exercised:
Repeat step 2 through 3 changing the address for the entire array verification (See Figure 17-2.)
• 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.
