Status of external pins
The status of the external pins during Idle and Power-down
mode is shown in Table 4. If the Power-down mode is
activated whilst accessing external Program Memory, the
port data that is held in the Special Function Register P2 is
restored to Port 2.
If the data is a logic 1, the port pin is held HIGH during the
Power-down mode by the strong pull-up transistor ‘p1’;
see Fig.9(a).

Power Control Register (PCON)
The reduced power modes are activated by software using this Special Function Register. PCON is not bit addressable.

Description of PCON bits
Note
1.
If logic 1s are written to PD and IDL at the same time, PD takes precedence. The reset value of PCON is (0XX00000).
