The SH7047 group has an on-chip high-speed static RAM. The on-chip RAM is connected to the
CPU, data transfer controller (DTC), and advanced user debugger (AUD) by a 32-bit data bus,
enabling 8, 16, or 32-bit width access to data in the on-chip RAM. Data in the on-chip RAM can
always be accessed in one cycle, providing high-speed access that makes this RAM ideal for use
as a program area, stack area, or data area. The contents of the on-chip RAM are retained in both
sleep and software standby modes.
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 24.2.2,
System Control Register (SYSCR).
