19.2.2
Enabling or disabling of part of the on-chip ROM area in the chip can be selected by means of the
EAE bit in BCRL. For details of the other bits in BCRL, see section 6.2.5, Bus Control Register L
(BCRL).
Bit 5—External Address Enable (EAE): Selects whether addresses H'010000 to H'03FFFF *
to be internal addresses or external addresses.
Notes: 1. Do not access a reserved area.
19.3
The on-chip ROM is connected to the CPU by a 16-bit data bus, and both byte and word data can
be accessed in one state. Even addresses are connected to the upper 8 bits, and odd addresses to
the lower 8 bits. Word data must start at an even address.
The on-chip ROM is enabled and disabled by setting the mode pins (MD2 to MD0) and the EAE
bit in BCRL. These settings are shown in tables 19.2 and 19.3.
