SADEN
This register enables the Automatic Address Recognition feature of the Serial
port 0. When a bit in the SADEN is set to 1, the same bit location in SADDR will
be compared with the incoming serial data. When SADEN.n is 0, then the bit
becomes a "don't care" in the comparison. This register enables the Automatic
Address Recognition feature of the Serial port 0. When all the bits of SADEN
are 0, interrupt will occur for any incoming address.

SWRESET/
REBOOT
(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 H/W REBOOT mode is running.

FBOOTSL The Program Location Select.
0: The Loader Program locates at the 64 KB AP Flash EPROM. 4KB LD
Flash EPROM is destination for re-programming.
1: The Loader Program locates at the 4 KB memory bank. 64KB AP Flash
EPROM is destination for re-programming.

FPROGEN FLASH EPROM 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.
