ATtiny87/ATtiny167
Signal Names
The ATtiny87/167 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.
Table 21-7.
Table 21-8.
This section describes how to parallel program and verify Flash Program memory, EEPROM
Data memory, Memory Lock bits, and Fuse bits in the ATtiny87/167. Pulses are assumed to
be at least 250 ns unless otherwise noted.
In this section, some pins of the ATtiny87/167 are referenced by signal names describing their
functionality during parallel programming, see
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
