(F04KMODE)
(MUST SET 0) (MUST SET 0)
Mnemonic: CHPCON
Address: 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.
4 ENAUXRAM
1 FBOOTSL
0 FPROGEN
1: Enable on-chip AUX-RAM.
0: Disable the on-chip AUX-RAM
The Loader Program Location Select.
0: The Loader Program locates at the 64K/32K Byte flash memory
bank.
1: The Loader Program locates at the 4KB flash memory bank.
Flash EPROM Programming Enable
1: Enable. The microcontroller switches to the programming flash
mode after entering the idle mode and waken up from interrupt.
The microcontroller will execute the loader program while in on-
chip programming mode.
0: Disable. The on-chip flash memory is read-only. In-system pro-
grammability is disabled.

BIT NAME
FUNCTION
7 PX3
External interrupt 3 priority high if set
6 EX3
External interrupt 3 enable if set
5 IE3
If IT3 = 1, IE3 is set/cleared automatically by hardware when interrupt is de-
tected/serviced
4 IT3
External interrupt 3 is falling-edge/low-level triggered when this bit is set/cleared
by software
3 PX2
External interrupt 2 priority high if set
2 EX2
External interrupt 2 enable if set
1 IE2
If IT2 = 1, IE2 is set/cleared automatically by hardware when interrupt is de-
tected/serviced
0 IT2
External interrupt 2 is falling-edge/low-level triggered when this bit is set/cleared
by software
