4. Operation Sequence in PC Card Mode
*1: The time for setting the DLCR, MAR, and BMPR registers may be included in the waiting time of 200
s.
*2: The STBY bit of DLCR7 is automatically set to 0.
*3: The STBY bit of DLCR7 is automatically set to 1.
In the PC card mode, the STBY bit of DLCR7 is set from the PwrDwn bit of CCR1 to as shown in *2 and *3. Direct
change (from 0 to 1 or from 1 to 0) is not allowed.
Standby state: The clock to each circuit stops but crystal oscillation does not.
Shutdown state: Crystal oscillation stops.
Operable state
