MTP805
(Rev. 0.9)
Revision 0.9 - 4 - 2000/07/19
FUNCTIONAL DESCRIPTIONS
1. 8051 CPU Core
MTP805 includes all 8051 functions with the following exceptions:
1.1 PSEN, ALE, #RD and #WR pins are disabled. The external RAM access is restricted to XFRs within the
MTP805.
1.2 Port0, port3.2, port3.3, port3.6 and port3.7 are not general-purpose I/O ports. They are dedicated to
special application.
1.3 #INT0 and #INT1 input pin is not provided, it is connected to special interrupt sources.
1.4 UART and Timer1 are not supported.
Note: All registers listed in this document reside in external RAM area (XFR). For internal RAM memory map
please refer to 8051 spec.
2. Memory Allocation
2.1 Internal Special Function Registers (SFR)
The SFR is a group of registers that are the same as standard 8051.
2.2 Internal RAM
There are total 256 bytes internal RAM in MTP805, same as standard 8052.
2.3 External Special Function Registers (XFR)
The XFR is a group of registers allocated in the 8051 external RAM area 00h - 2Fh. Most of the registers are
used for USB function. Program can initialize Ri value and use "MOVX" instruction to access these registers.
