Revision A4
6.13.1 CHPCON (BFH)
BIT
NAME
FUNCTION
7
SWRESET
(F04KMODE)
When this bit is set to 1, and both FBOOTSL and FPROGEN are set to 1. It
will enforce microcontroller reset to initial condition just like power on reset.
This action will re-boot the microcontroller and start to normal operation.
To read this bit can determine that the F04KBOOT mode is running.

Reserve.
5
ENEEPROM Enable on-chip 128 bytes EEPROM.
4
ENAUXRAM Enable on-chip 512 bytes auxiliary RAM.

1
FBOOTSL
The loader program location selection.
= 0: loader program in 32K memory bank.
= 1: loader program in 4K memory bank.
0
FPROGEN
In system programming enable flag.
= 1: enable. The CPU switches to the programming flash mode after
entering the idle mode and waken up from interrupt. The CPU will
execute the loader program while in on-chip programming mode.
= 0: disable. The on-chip FLASH EPROM read-only. In-system
programmability is inhibit.
6.14 MXPSR (A2H)
BIT
NAME
FUNCTION
7
BUSY
EEPROM BUSY signal.
1: EEPROM is writing.
6-2
-
Reserved.
1-0
ADDRPNT
Address pointer by MOVX instruction
0: read or write lower 256 byte Auxiliary RAM by pointer of R0 or R1 register
1: read or write Higher 256 byte Auxiliary RAM by pointer of R0 or R1
register
2: 128 byte EEPROM by pointer of R0 or R1 register
6.15 Interrupt System
External events and the real-time-driven on-chip peripherals require service by the CPU
asynchronous to do execution of any particular section of code. To tie the asynchronous actives of
these functions to normal program execution, a multiple-source, two-priority-level, nested interrupt
system is provided. The W78E858 acknowledges interrupt requests from fourteen sources as below:
INT0 and INT1
