Section 20 RAM
This LSI has an 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.
The on-chip RAM can be enabled or disabled by means of the RAME bit in the system control
register (SYSCR). For details on the system control register (SYSCR), see section 3.2.2, System
Control Register (SYSCR).
