18.1
The H8S/2339 has 32 kbytes of on-chip high-speed static RAM, the H8S/2338 and H8S/2332
have 8 kbytes. The RAM is connected to the CPU by a 16-bit data bus, enabling one-state access
by the CPU to both byte data and word data. This makes it possible to perform fast word data
transfer.
The on-chip RAM can be enabled or disabled by means of the RAM enable bit (RAME) in the
system control register (SYSCR).
