71M652X Software User’s Guide
All 80515 instructions are binary code compatible and perform the same functions as they do with the industry standard
8051. The following tables give a summary of the instruction set cycles of the 80515 MPU core.
Table 6-7 and Table 6-8 contain notes for mnemonics used in instruction set tables.
Table 6-9 through Table 6-17 show the instruction hexadecimal codes, the number of bytes, and the number of
machine cycles required for each instruction to execute.

TERIDIAN Proprietary
Only byte operations on the whole WDI register should be used when
writing. This multi-purpose register contains the following bits:
Bit 0 (IE_XFER): XFER Interrupt Flag:
This flag monitors the XFER_BUSY interrupt. It is set by hardware
and must be cleared by the interrupt handler
Bit 1 (IE_RTC): RTC Interrupt Flag:
This flag monitors the RTC_1SEC interrupt. It is set by hardware and
must be cleared by the interrupt handler
Bit 7 (WD_RST): WD Timer Reset:
The WDT is reset when a 1 is written to this bit.
Interrupt inputs. The MPU may read these bits to see the input to
external interrupts INT0, INT1, up to INT6. These bits do not have
any memory and are primarily intended for debug use
