• Manufacturer Part Number: zic2410
• Description: Single-chip Solution, Compliant With Zigbee
• Manufacturer: California Eastern Laboratories

DATA POINTER (DPH: 0x83, DPL: 0x82)
Data pointer consists of a high byte (DPH) and a low byte (DPL) to support 16-bit address. It can be
accessed by 16-bit register or by two 8-bit registers respectively.
AUXR1 (AUXILIARY CONTROL REGISTER, 0xA2)
This register is used to implement Dual DPTR functions. Physically, DPTR consists of DPTR0 and
DPTR1. However, DPTR0 and DPTR1 can be accessed depending on the DPS value of AUXR1
respectively. In other words, they cannot be accessed at the same time.
P3 (0xB0)
This port register can be used as other functions besides general purpose I/O.

Dual DPTR Select: Used to select either DPTR0 or DPTR1.
When DSP is ‘0’, DPTR0 is selected. When DSP is ‘1’, DPTR1 is
selected.
This port register is used as a general purpose I/O port (12mA
Drive).
When Timer3 is operated as a PWM mode, it outputs PWM wave
(PWM3) of Timer3.
When port register is used as UART1, it is used as a CTS signal
(CTS1) of UART1.
When used as a Master mode, SPI Slave Select signal is
outputted. When used as a Slave mode, this port register
receives SPI Slave Select signal. This signal activate in low
This port register is used as a general purpose I/O port (12mA
Drive)
When Timer2 is operated as a PWM mode, it outputs PWM wave
(PWM2) of Timer2.
When port register is used as UART1, it is used as a RTS signal
(RTS1) of UART1.
When used as a Master mode, SPI clock is outputted. When
used as a Slave mode, this port register receives SPI clock.
This port register is used as a general purpose I/O port.
When Timer1 is operated as a COUNTER mode, it is operated as
a counter input signal (T1) of Timer1.
When port register is used as UART0, it is used as a CTS signal
(CTS0) of UART0.
In a Master mode or a Slave mode, this port register is used for
outputting SPI data.
When port register is used as QUAD function, it is used as the
input signal of YB value.
This port register is used as a general purpose I/O port.
When Timer0 is operated as a COUNTER mode, it is operated as
a counter input signal (T0) of Timer0.
When port register is used as UART0, it is used as a RTS signal
(RTS0) of UART0.
