GENERAL DESCRIPTION
The Z86E03/E06 are One-Time Programmable (OTP) members of the Z8® microcontroller family allowing easy software development, debug, and prototyping for small production runs that are not economically desirable with a masked ROM version.
Three address spaces, the Program Memory, Register File, and Expanded Register File (ERF), support a wide range of memory configurations.
Through the ERF, the designer has access to four additional control registers that provide extra peripheral devices, I/O ports, register addresses, an SPI receive buffer and SPI compare register.
For applications demanding powerful I/O capabilities, the Z86E03/E06's dedicated input and output lines are grouped into two ports, and are configurable under software control to provide timing, status signals, or parallel I/O.
Notes: All Signals with a preceding front slash, "/", are active Low, e.
g.
: B//W (WORD is active Low); /B/W (BYTE is active Low, only).
