Reading the 8 MHz RC Oscillator Calibration Byte
Reading the Temperature Sensor Parameter Bytes
The algorithm for reading the 8 MHz RC Oscillator Calibration byte is as follows (refer to
gramming the Flash” on page 256
The algorithm for reading the Temperature Sensor parameter bytes is as follows (refer to
gramming the Flash” on page 256
Both the Flash and EEPROM memory arrays can be programmed using the serial SPI bus while
RESET is pulled to GND. The serial interface consists of pins SCK, MOSI (input) and MISO (out-
put). After RESET is set low, the Programming Enable instruction needs to be executed first
before program/erase operations can be executed.

Note:
1. A: Load Command “0000 1000
2. B: Load Address Low Byte, 0x00.
3. Set OE to “0”, and BS1 to “1”. The 8 MHz RC Oscillator Calibration byte can now be
