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 in logic-1 can determine that the F04KBOOT mode is running.
6 - Reserve.
5 - Reserve.

ENAUXRAM
1: Enable on-chip AUX-RAM.
0: Disable the on-chip AUX-RAM
3 0 Must set to 0.
2 0 Must set to 0.
1 FBOOTSL The Program Location Select.
0: The Loader Program locates at the 64 KB APROM. 4KB LDROM is
destination for re-programming.
1: The Loader Program locates at the 4 KB memory bank. 64KB APROM is
destination for re-programming.
0 FPROGEN
MTP-ROM Programming Enable.
= 1: enable. The microcontroller enter the in-system programming mode after
entering the idle mode and wake-up from interrupt. During in-system
programming mode, the operation of erase, program and read are
achieve when device enters idle mode.
= 0: disable. The on-chip flash memory is read-only. In-system
programmability is disabled.
