Section 19 RAM
This LSI includes 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 RAM can be enabled or disabled using the RAME bit in the system control register (SYSCR).
For details on SYSCR, see section 3.2.2, System Control Register (SYSCR).
