    0838H–AVR–03/02
    the self-timed write instruction in the Serial Programming mode. During programming,
    the supply voltage must be in accordance with Table 13.
    Parallel Programming
    This section describes how to parallel program and verify Flash program memory,
    EEPROM data memory, Lock bits and Fuse bits in the AT90S1200.
    Figure 30. Parallel Programming
    Signal Names
    In this section, some pins of the AT90S1200 are referenced by signal names describing
    their function during parallel programming rather than their pin names, see Figure 30
    and Table 14. Pins not described in Table 14 are referenced by pin names.
    The XA1/XA0 pins determines the action executed when the XTAL1 pin is given a posi-
    tive pulse. The coding is shown in Table 15.
    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 16.
