RESET

Reset (input, active low). The

ST9+ is initialised by the Reset

signal. With the deactivation of

RESET, program execution be-

gins from the memory location

pointed to by the vector con-

tained in memory locations 00h

and 01h

OSCIN

OSCIN is the input of the oscilla-

tor inverter and internal clock

generator. OSCIN and OSCOUT

connect a parallel-resonant crys- 19 20

tal (3 to 5 MHz), or an external

source to the on-chip clock oscil-

lator and buffer

OSCOUT

OSCOUT is the output of the os-

cillator inverter
