28.7. Parallel Programming Parameters, Pin Mapping, and Commands
This section describes how to parallel program and verify Flash Program memory, EEPROM Data
memory, Memory Lock bits, and Fuse bits in the device. Pulses are assumed to be at least 250ns unless
otherwise noted.
28.7.1. Signal Names
In this section, some pins of this device are referenced by signal names describing their functionality
during parallel programming, please refer to Figure. Parallel Programming and Table. Pin Name Mapping
in this section. Pins not described in the following table are referenced by pin names.
The XA1/XA0 pins determine the action executed when the XTAL1 pin is given a positive pulse. The bit
coding is shown in the table, XA1 and XA0 Coding.
When pulsing WR or OE, the command loaded determines the action executed. The different Commands
are shown in the table, Command Byte Bit Coding Command Byte Command Executed.
