Reset circuitry allows the controller to be easily placed in a predefined default condition. On entry to this reset state,
the following occur:
All SFRs are reset to the predefined values noted in the SFR detailed descriptions. The contents of internal data mem-
ory are unaffected during a reset; any previously stored data is preserved. However, since the stack pointer SFR is
reset, the stack is effectively lost even though the data on the stack is not altered.
The Port I/O latches are reset to 0xFF (all logic ones) in open-drain mode. Weak pull-ups are enabled during and after
the reset. For VDD Monitor and Power-On Resets, the /RST pin is driven low until the device exits the reset state.
On exit from the reset state, the program counter (PC) is reset, and the system clock defaults to the internal oscillator.
