Products in the 78K0/LF2 can each access a 64 KB memory space. Figures 3-1 to 3-6 show the memory maps.
Cautions 1. Regardless of the internal memory capacity, the initial values of the internal memory size
Notes 1. The ROM and RAM capacities of the products with the on-chip debug function can be debugged

2. The PD78F0376, 78F0376D, 78F0386, and 78F0386D have internal ROM of 96 KB, respectively.
(78K0/LF2)
2. To set the memory size, set IMS and then IXS. Set the memory size so that the internal ROM

However, the set value of IMS of these devices is the same as those of the 48 KB product because
memory banks are used. For how to set the memory banks, see 3.6 Memory Bank Select Register
