Section 13 RAM
This LSI has an on-chip high-speed static RAM. The RAM is connected to the CPU by a 16-bit
data bus and is connected to the DMAC by a 32-bit data bus, enabling one-state access to byte
data, word data, and longword data (note that two-state access is used when the RAM is accessed
by using the longword access instruction such as MOV.L by the CPU).
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), refer to section 3.2.2,
System Control Register (SYSCR).
