18.1
The size of the on-chip ROM is 60 kbytes in the H8/3437, 48 kbytes in the H8/3436, and 32
kbytes in the H8/3434. The on-chip ROM is connected to the CPU via a 16-bit data bus. Both byte
data and word data are accessed in two states, enabling rapid data transfer.
The on-chip ROM is enabled or disabled depending on the inputs at the mode pins (MD

Mode 1 (expanded mode)
Mode 2 (expanded mode)
Mode 3 (single-chip mode)
The PROM versions (H8/3437 ZTAT and H8/3434 ZTAT) and flash-memory version (H8/3437
F-ZTAT and H8/3434 F-ZTAT ) can be set to writer mode and programmed with a general-
purpose PROM programmer. In the H8/3437, the accessible ROM addresses are H'0000 to
H'EF7F (61,312 bytes) in mode 2, and H'0000 to H'F77F (63,360 bytes) in mode 3. For details, see
