Protest the miss-writing to the RAM
Protest the miss-writing to the SFR
Successive approximation type AD converter test function
RAM parity error check and generates a reset on error (enable/disable reset
by SFR, with reset status flag and parity error flag)
Make a reset in case the CPU executes an instruction in the unused area
(enable/disable reset by the code option, with reset status flag)
Monitor to check whether the oscillation of the high-speed and low-speed
clocks are normal
Detect data error in the flash memory or data error in communications
Make the UART self-test
Make the SSIO self-test
2
Make the I C self-test function
WDT counter read function
General port self-test function
Switch automatically to the low-speed RC oscillation in case the low-speed
crystal oscillation stopped
Control interrupts generated by RAM parity error, automatic CRC calculation
completion, data flash erase/program completion.
