17.1.2
The on-chip RAM is controlled by SYSCR. Table 17.1 gives the address and initial value of
SYSCR.
Table 17.1 System Control Register
H'EE012
Note:
17.2
One function of SYSCR is to enable or disable access to the on-chip RAM. The on-chip RAM is
enabled or disabled by the RAME bit in SYSCR. For details about the other bits, see section 3.3,
System Control Register (SYSCR).
Bit 0—RAM Enable (RAME): Enables or disables the on-chip RAM. The RAME bit is
initialized at the rising edge of the input at the RES pin. It is not initialized in software standby
mode.
