9.2. Program 2: Read ADC result from Channel 1

;; Inherit from program 1

;; 8-bit ADC result of channel 1 in ( ad_out_h, ad_out_l)

;; ad_out_h is bit7~bit4, ad_out_l is bit3~bit0

@Read_ADC

#0, #0, #1

;;get ADC result from Ch1 in ( ad_out_h, ad_out_l)

…

9.3. Program 3: Read Digital Input data from Ch4, Ch3, CH2

;; Inherit from program 1

;; After Reading,

;; Port_h.0 = Input of Ch4

;; Port_l.3 = Input of Ch3

;; Port_l.2 = Input of Ch2

@Read_Port

;; 8-bit Data

(port_h, port_l)

…

9.4. Program 4: Power-down SNAD01C and Host, and Wake-up

;; Inherit from program 1

;; Enter Power-down Mode (0)

@Set_Control_Reg #0, #1, #0, #0

;; Set Control Registers RF and MB is 0

@Power_Down_0

;;SNAD01C enters power-down Mode (0)

end

;; HOST (SNC520) enter power-down
