17.1
The H8S/2350 Group has 2 kbytes of on-chip high-speed static RAM. 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).
