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 (output). After RESET is set low, the Programming Enable instruction needs to be exe-
cuted first before program/erase operations can be executed.
