49 / 145 page  SN8P1700 8-bit micro-controller build-in 12-bit ADC SONiX TECHNOLOGY CO., LTD Page 49 Revision 1.94 5 5 5 SYSTEM REGISTER OVERVIEW The system special register is located at 80h~FFh. The main purpose of system registers is to control the peripheral hardware of the chip. Using system registers can control I/O ports, SIO, ADC, PWM, timers and counters by programming. The Memory map provides an easy and quick reference source for writing application program. To accessing these system registers is controlled by the select memory bank (RBANK = 0) or the bank 0 read/write instruction (B0MOV, B0BSET, B0BCLR…).
