Bit 4 (T): Time-out bit  
Set to 1 by the "SLEP" and "WDTC" command, or during power up and  
reset to 0 by WDT timeout.  
Bit 3 (P): Power down bit  
Set to “1” during power on or by a "WDTC" command and reset to “0” by a  
"SLEP" command.

Remarks  
WDT wakes up from sleep mode  
WDT times out (not in sleep mode)  
/RESET wakes up from sleep  
Power up  
Low pulse on /RESET  
× = don't care  
Bit 2 (Z): Zero flag  
Bit 1 (DC): Auxiliary carry flag  
Bit 0 (C): Carry flag  
6.2.5 R4 (RAM Select Register)  
Bit 7 (VDB): Voltage Detector. This is a read only bit. When VDD pin voltage is lower  
then Vdet (select by LVDS0~LVDS1) this bit will be cleared.  
0 : low voltage is detected  
1 : low voltage is not detected or LVD function is disabled  
Bit 6 (BNC): Bank Control Register.  
0 : allow to access only Bank 0 registers  
1 : Allow to access all registers of any Bank  
Bits 5~0: are used to select up to 64 registers in the indirect addressing mode.  
See the configuration of the data memory. User can use BANK instruction  
to change bank.
