instruction execution cycle

Fig.46 External access timing.

T being the half period of the internal

6 MHz oscillator for normal external

access and of TCLK for emulation,

programming and test modes.

The minimum duration of one cycle is 6T.

It can be extended by increments of

[0 to n]T if the execution of an instruction

needs more time (dependant of VDD, T,

Temperature, Opcode).

Execution of an op-code goes in parallel

with the external access cycle for the

next sequential byte. Eventually an

already fetched byte is discarded

depending on the executed instruction

(e.g. any jump or return).
