Bit 0 ~ Bit 7 (CN10 ~ CN17) : Counter1's buffer that user can read and write.
Counter1 is a 8-bit up-counter with 8-bit prescaler that user can use RC PAGE1 to preset and read the
counter.(write
preset) After a interruption , it will reload the preset value.
Example for writing :
MOV 0x0C, A ; write the data at accumulator to counter1 (preset)
Example for reading :
MOV A, 0x0C ; read the data at counter1 to accumulator

Ps. To change the display duty must set the "LCD_C1 ,LCD_C0" to "00".
The controller can drive LCD directly. The LCD block is made up of common driver, segment driver,
display LCD RAM, common output pins, segment output pins and LCD operating power supply. The basic
structure contains a timing control. This timing control uses the basic frequency 32.768KHz to generate the
proper timing for different duty and display access.
RD PAGE0 Bit 0 ~ Bit 2 are LCD control bits for LCD driver. These LCD control bits determine the duty,
the number of common and the frame frequency. The LCD display (disable, enable, blanking) is controlled
by Bit 1 and Bit 2. The driving duty is decided by Bit 0. The display data is stored in LCD RAM which
address and data access controlled by registers R5 PAGE1 and R6 PAGE1.
