Flash Memory Operation
Table 24.11 "Flash Memory Access from the Internal CPU" can also be used.
Address setting can be performed according to the "Normal bus write cycle address
configuration" from the first bus cycle.
"0" is recommended" can be changed as necessary.
(5) Address bit configuration for bus write cycles
PBA: Protection bit address (Set the seventh bus write cycle address for protection bit programming)
PA: Program page address (Set the fourth bus write cycle address for page programming operation)
