Table 20-5 shows the Reset conditions for the RCON
register. Since the control bits within the RCON register
are R/W, the information in the table means that all the
bits are negated prior to the action specified in the
condition column.
TABLE 20-5:
INITIALIZATION CONDITION FOR RCON REGISTER: CASE 1
Table 20-6 shows a second example of the bit
conditions for the RCON register. In this case, it is not
assumed the user has set/cleared specific bits prior to
action specified in the condition column.
