the self-timed write operation in the serial programming mode. During programming, the
supply voltage must be in accordance with Table 26.
Table 26. Supply Voltage during Programming
This section describes how to parallel program and verify Flash program memory,
EEPROM data memory, Lock bits and Fuse bits in the AT90S8515.
In this section, some pins of the AT908515 are referenced by signal names describing
their function during parallel programming. See Figure 60 and Table 27. Pins not
described in Table 27 are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a posi-
tive pulse. The bit coding are shown in Table 28.
When pulsing WR or OE, the command loaded determines the action executed. The
command is a byte where the different bits are assigned functions as shown in Table 29.
