9 / 65 page ST10C167 9/65 RSTOUT 141 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. NMI 142 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 ST10C167 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. VAREF 37 - Reference voltage for the A/D converter. VAGND 38 - Reference ground for the A/D converter. RPD 84 - This pin is used as the timing pin for the return from powerdown circuit and power-up asynchronous reset. VDD 17, 46, 56, 72, 82, 93, 109, 126, 136, 144 - Digital Supply Voltage: = + 5V during normal operation and idle mode. > + 2.5V during power down mode VSS 18, 45, 55, 71, 83, 94, 110, 127, 139, 143 - Digital Ground.
