Section 16 RAM
The H8S/2218 and H8S/2212 have 12 kbytes of on-chip high-speed static RAM. The H8S/2217
and H8S/2211 have 8 kbytes of on-chip high-speed static RAM. The H8S/2210 and H8S/2210S
has 4 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). For details on SYSCR, refer to section 3.2.2, System Control
Register (SYSCR).
