2017年10月12日 · io空间：pci标准规定的io地址空间最大可以有4G，但是x86只实现了64k的大小。 io空间用来实现早期兼容的外设寄存器的访问（IO端口），和用来映射pci外设的io空间。

The CAT25640 is a EEPROM Serial 64−Kb SPI device internally organized as 8Kx8 bits. This features a 64−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines.

The CAT28C64B is a fast, low power, 5V-only CMOS Parallel EEPROM organized as 8K x 8-bits. It requires a simple interface for in-system programming. On-chip address and data latches, self-timed write cycle with auto-clear and VCC power up/down write protection eliminate additional timing and protection hardware.
