24. Chip Erase
Function:
1.
FFH programmed to every address location.
2.
FFH programmed to User Signature Row if User Row Fuse bit is enabled.
3.
Lockbit1 and Lockbit2 programmed to “unlock” state.
Usage:
1.
Apply “0001” TestCode to P3.7, P3.5, P3.4, P3.3.
2.
Pulse P3.2 low for 1 s.
3.
Wait 4 ms, monitor P3.1, or poll data.
Note:
This and the following waveforms are not to scale.

25. Load X-Address
Function:
1.
Loads the X-Address register with data on Port P1. The loaded address will select the
page for subsequent write/read commands. The X-Address is equivalent to bits [11:5]
of the full byte address.
2.
Resets the Y-Address counter to 00H. The Y-Address is equivalent to bits [4:0] of the
full byte address and selects a byte within a page.
Usage:
1.
Apply “1101” TestCode to P3.7, P3.5, P3.4, P3.3.
2.
Drive Port P1 with 8-bit X-address data.
3.
Pulse XTAL1 high for at least 100 ns. The address is latched on the falling edge of
XTAL1.
