    关于SN8P1602B单片机
    The SN8P1602B is an 8-bit micro-controller utilized CMOS technology and featured with low power consumption and high performance by its unique electronic structure.SN8P1602B is designed with the excellent IC structure including the program memory up to 1K-word OTP ROM, data memory of 48-bytes RAM, one 8-bit timer (TC0), a watchdog timer, two interrupt sources (TC0, INT0), and 4-level stack buffers. Besides, user can choose desired oscillator configuration for the controller. There are four external oscillator configurations to select for generating system clock, including High/Low speed crystal, ceramic resonator or cost-saving RC. SN8P1602B also includes an internal RC oscillator for slow mode controlled by programming.
  The SN8P1602B provides the program memory up to 1024 * 16-bit to be addressed and is able to fetch instructions through 10-bit wide PC (Program Counter). It can look up ROM data by using ROM code registers (R, Y, Z).
   1-word reset vector addresses
   1-word interrupt vector addresses
   1K words general purpose area
   5-word reserved area
  All of the program memory is partitioned into three coding areas. The first area is located from 00H to 03H(The Reset vector area), the second area is a reserved area 04H ~07H, the 3rd area is for the interrupt vector and the user code area from 0008H to 03FEH/0FFEH. The address 08H is the interrupt enter address point.
