the time the WAIT instruction is executed.
Mnemonic
This MOVE applies only to the case where two reads are performed in parallel from the X memory.
The STOP instruction disables the internal clock oscillator. After the clock is turned on, an internal
The WAIT instruction takes a minimum of 16 cycles to execute when an internal interrupt is pending at
