FUNCTIONAL DESCRIPTION
(Continued)
EPROM MODE
Table 14 shows the programming voltages of each pro-
gramming mode. Table 15, and figures that follow show
the programming timing of each programming mode. Fig-
ure 38 shows the circuit diagram of a Z86E40 program-
ming adapter, which adapts from 2764A to Z86E40 and
Figure 39 shows the Z86E30/E31 Programming Adapter
Circuitry. Figure 40 shows the flowchart of an Intelligent
Programming Algorithm, which is compatible with 2764A
EPROM (Z86E40 is 4K EPROM, 2764A is 8K EPROM).
Since the EPROM size of Z86E30/E31/E40 differs from
2764A, the programming address range has to be set from
0000H to 0FFFH for the Z86E30/E40 and 0000H to 07FFH
for Z86E31. Otherwise, the upper portion of EPROM data
will overwrite the lower portion of EPROM data. Figure 39
shows the adaptation from the 2764A to Z86E30/E31.
Note:
EPROM Protect feature allows the LDC, LDCI, LDE,
and LDEI instructions from internal program memory. A
ROM lookup table can be used with this feature.
During programming, the V
PP
input pin supplies the pro-
gramming voltage and current to the EPROM. This pin is
also used to latch which EPROM mode is to be used (R/W
EPROM or R/W Option bits). The mode is set by placing
the correct mode number on the least significant bits of the
address and raising the EPM pin above V. After a setup
time, the V
PP
pin can then be raised or lowered. The
latched EPROM mode will remain until the EPM pin is re-
duced below V
H
.
EPROM R/W mode allows the programming of the user
mode program ROM.
Option Bit R/W allows the programming of the Z8 option
bits. When the device is latched into Option Bit R/W mode,
the address must then be changed to 63 decimals
(000000111111 Binary). The Options are mapped into this
address as follows:
Table 14 gives the proper conditions for EPROM R/W op-
erations, once the mode is latched.
