Calibration Byte
Parallel Programming Parameters, Pin Mapping, and Commands
Signal Names
The ATA6602/ATA6603 has a byte calibration value for the internal RC Oscillator. This byte
resides in the high byte of address 0x000 in the signature address space. During reset, this byte
is automatically written into the OSCCAL Register to ensure correct frequency of the calibrated
RC Oscillator.
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATA6602/ATA6603. Pulses are assumed
to be at least 250 ns unless otherwise noted.
In this section, some pins of the ATA6602/ATA6603 are referenced by signal names describing
their functionality during parallel programming (see
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
When pulsing WR or OE, the command loaded determines the action executed. The different
Commands are shown in
