问 小弟使用Z85C30芯片进行HDLC协议通信，现在芯片的初始化不能通过，那位大哥使用过该芯片，帮帮小弟吧！ 答 1: 85c30我已救了一个人,但不知是否救活?
我用85C30多年,现在遇到的问题是;
1)CRC与一般的不同,
2)传码先后不同
3)同步难解决
我可给你初始化程序

void sccinit(void)                             //Z85C30初始化
{
XBYTE[Scca]=0x09;                         //wr9 reset
XBYTE[Scca]=0xc0;                         //hardware reset

XBYTE[Scca]=0x03;                         //Rx set
XBYTE[Scca]=0xd0;                         //wr3 reset

XBYTE[Scca]=0x05;                         //Tx set wr5 reset
XBYTE[Scca]=0x60;                         //8bit no CRC pormis

XBYTE[Scca]=0x06;                         //sync word wr6
XBYTE[Scca]=0xab;
XBYTE[Scca]=0x07;                         //sync word WR7
XBYTE[Scca]=0xab;

XBYTE[Scca]=0x09;                         //WR9  prohibit  aLL int
XBYTE[Scca]=0x00;

XBYTE[Scca]=0x09;                         //WR9  repeat two times
XBYTE[Scca]=0x00;

XBYTE[Scca]=0x0a;                         //wr10 set
XBYTE[Scca]=0x20;                         //20 NRZI mode

XBYTE[Scca]=0x0e;                         //wr14 set  SCC enabLe
XBYTE[Scca]=0x23;

XBYTE[Scca]=0x03;                         //wr3 set
XBYTE[Scca]=0xd1;                         //Rx enabLe

XBYTE[Scca]=0x05;                         //wr3 set
XBYTE[Scca]=0x60;       //tx enabLe 答 2: song9644 谢谢您不知道您用Z85C30做过HDLC通信没有，我现在调试不出，请您指教！ 答 3: z我没说清楚,CRC 就是HDLC方式下的校验码.与标准CRC有所不同,如两端均用Z85C30,则无问题,如与其它产品对接,调式较难.

请问:如果Z85c30不采用总线方式，该怎么寻址寄存器。

void main (void)
{
uchar ucRet;
Init_Device();

put_reg(0,WR0,0xc4);
ucRet=get_reg(0,WR0);
while(1) {
 }
}

现在想从任意一个寄存器中，例如WR0,写一个控制字再读出来，测试Z片工作没，怎么实现不了（读出来的始终是我自己定义的WR0的地址 

//寄存器偏移地址
#define WR0    0x00
#define WR1    0x01

......
）。
