Revision A1
LDAP: This bit is Read Only. High: device is executing the program in LDROM. Low: device is
executing the program in APROM.
LDSEL: Loader program residence selection. Set to high to route the device fetching code from
LDROM.
ENP: In System Programming Mode Enable. Set this be to launch the ISP mode. Device will
operate ISP procedures, such as Erase, Program and Read operations, according to
correlative SFRs settings. During ISP mode, device achieves ISP operations by the way of
IDLE state. In the other words, device is not indeed in IDLE mode is set bit PCON.1 while ISP
is enabled. Clear this bit to disable ISP mode, device get back to normal operation including
IDLE state.
