This bit can be read from or written to. However,
the write value should always be 0.
Refresh Counter Clock Select
These bits select the clock to be used to increment
the refresh counter. When the input clock is
selected with bits RTCK2 to RTCK0, the refresh
counter begins counting up.
000: Count operation halted
001: Count on φ/2
010: Count on φ/8
011: Count on φ/32
100: Count on φ/128
101: Count on φ/512
110: Count on φ/2048
111: Count on φ/4096
Refresh Control
Refresh control can be performed. When refresh
control is not performed, the refresh timer can be
used as an interval timer.
0: Refresh control is not performed
1: Refresh control is performed
CBR Refresh Mode
Selects CBR refreshing performed in parallel with
other external accesses, or execution of CBR
refreshing alone.
When the continuous synchronous DRAM space is
set, this bit can be read/written, but the setting
contents do not affect operations.
0: External access during CAS-before-RAS
1: External access during CAS-before-RAS
refreshing is enabled
refreshing is disabled
