2.1. the name (long) of the automatic pointer 1 in the Suite version is different from that in the Keil version (short), but it is well compatible. The Compatibility process is as follows:

# Define autoptr1h autoptrh1 // For backwards compatibility with examples

# Define autoptr1l autoptrl1 // For backwards compatibility with examples

# Define aptr1h autoptrh1 // For backwards compatibility with examples

# Define aptr1l autoptrl1 // For backwards compatibility with examples

2.2. fx2regs. h provided by suite3.4.7 defines each bit of the IO port. The Keil version does not. The IO port bit is defined as follows:

SFr IOA = 0x80;

/* IOA */

Sbit pa0 = 0x80 + 0;

Sbit pa1 = 0x80 + 1;

Sbit pa2 = 0x80 + 2;

Sbit pa3 = 0x80 + 3;

??

Sbit pa4 = 0x80 + 4;

Sbit pa5 = 0x80 + 5;

Sbit 6 = 0x80 + 6;

Sbit pa7 = 0x80 + 7;
