O Internal Reset Indication Output. This pin is set to a low level when the

part is executing either a hardware-, a software- or a watchdog-timer

reset. RSTOUT remains low until the EINIT (end of initialization) instruc-

tion is executed.

I

Non-Maskable Interrupt Input. A high to low transition at this pin causes

the CPU to vector to the NMI trap routine. If bit PWDCFG = ‘0’ in

SYSCON register, when the PWRDN (power down) instruction is exe-

cuted, the NMI pin must be low in order to force the ST10F167 to go into

power down mode. If NMI is high and PWDCFG =’0’, when PWRDN is

executed, the part will continue to run in normal mode.

If not used, pin NMI should be pulled high externally.

- Reference voltage for the A/D converter.

- Reference ground for the A/D converter.

- Flash programming voltage (ST10F167 ONLY).

This pin accepts the programming voltage for ST10F167 derivatives with

on-chip Flash memory.

It is used also as the timing pin for the return from powerdown circuit and

power-up asynchronous reset.

- Digital Supply Voltage:

= + 5 V during normal operation and idle mode.

> + 2.5 V during power down mode

- Digital Ground.
