Given the low number of the commands, it is very much easier to learn the mnemonic with minimum effort
Standard contents are an A/D converter with 10 bit resolution, master I²C, 3 timers ('6 bit), 1 timer (8 Bit), watchdog, hardware multiply (8 x 8) and a programmable brown out reset. The integrated PLL function enables also the operation of the microcontroller with external oscillator clock pulse up to 40 MHz
The ROMLESS types (PIC18Cx01) enable a memory addressing up to 2 Mbytes
There is upwards compatibility of the family PIC16C... as well as that of the family PIC17C...
