BIT
NAME
FUNCTION
7
W: SWRESET
R: REBOOT
When FBOOTSL and FPROGEN are set to 1, set this bit to 1 to force the
microcontroller to reset to the initial condition, just like power-on reset.
This action re-boots the microcontroller and starts normal operation.
Read this bit to determine whether or not a hardware reboot is in progress.
Reserved
Program Location Selection. This bit should be set before entering ISP
mode.
0: The Loader Program is in the 64-KB AP Flash EPROM. The 4-KB LD
Flash EPROM is the destination for re-programming.
1: The Loader Program is in the 4-KB memory bank. The 64-KB AP Flash
EPROM is the destination for re-programming.
FLASH EPROM Programming Enable.
1: Enable in-system programming mode. In this mode, erase, program and
read operations are achieved during device enters idle state.
0: Disable in-system programming mode. The on-chip flash memory is
read-only.

CHPCON has an unrestricted read access, however, the write access is protected by timed-access
protection. See the section of timed-access protection for more information.
