; FC430 ES417 Demo - Digital Fan Control w/ Tachometer (IAR EW430 ASM version)
;
; Description: Drives cooling fan speed based on thermistor temperature
; Results: Displays tachometer and temperature on SoftBaugh SBLCDA4 LCD
; ACLK = UCLK0 = LFXT1 = 32.768 kHz
; MCLK = SMCLK = 32*ACLK = DCO = ~1.048576 MHz
; (external watch crystal is required on XIN XOUT for ACLK)
