Section 12 Bus State Controller (BSC)
Bits 5 to 3—Clock Select Bits (CKS2 to CKS0): Select the clock input to RTCNT. The source
clock is the external bus clock (BCLK). The RTCNT count clock is CKIO divided by the specified
ratio. The specified ratios are shown below in the normal external bus clock. Before specifying
the CKS2 to CKS0 of RTCST, the RTCOR must be specified.
Bit 5: CKS2

Bit 2—Refresh Count Overflow Flag (OVF): The OVF status flag indicates when the number of
refresh requests indicated in the refresh count register (RFCR) exceeds the limit set in the LMTS
bit of RTCSR.
Bit 2: OVF
0
1
Note: * Contents don't change when 1 is written to OVF.
Bit 1—Refresh Count Overflow Interrupt Enable (OVIE): OVIE selects whether to suppress
generation of interrupt requests by OVF when the OVF bit of RTCSR is set to 1.
Bit 1: OVIE

Description
RFCR has not exceeded the count limit value set in LMTS
Clear Conditions: When 0 is written to OVF
RFCR has exceeded the count limit value set in LMTS
Set Conditions: When the RFCR value has exceeded the count limit value
set in LMTS*
