    The provision of Flash type Program Memory provides the user with a means of convenient and easy upgrades and modifications to their programs on the same device. As an additional convenience, Holtek has provided a means of programming the microcontroller in- circuit using a 4-pin interface. This provides manufacturers with the possibility of manufacturing their circuit boards complete with a programmed or un-programmed microcontroller, and then programming or upgrading the program at a later stage.

    Users can use the OCDS function to emulate the device behavior by connecting the OCDSDA and OCDSCK pins to the Holtek HT-IDE development tools. The OCDSDA pin is the OCDS Data/Address input/output pin while the OCDSCK pin is the OCDS clock input pin. When users use the OCDS function for debugging, other functions which are shared with the OCDSDA and OCDSCK pins in the device will have no effect.

Before the MCU enters the DEEP SLEEP mode, the system settings should be backed up using the application program in advance. 2. When PWDN=1 and the HALT instruction is executed, the MCU will enter the DEEP SLEEP mode.

  • Page 51: Standby Current Considerations

    BC68F2130/BC68F2140/BC68F2150 Sub-1GHz RF Transmitter Flash MCU with OCDS Standby Current Considerations As the main reason for entering the DEEP SLEEP, SLEEP or IDLE Mode is to keep the current consumption of the devices to as low a value as possible, perhaps only in the order of several micro- amps except in the IDLE1 and IDLE2 Mode, there are other considerations which must also be taken into account by the circuit designer if the power consumption is to be minimised.

After a reset, all of the I/O data and port control registers will be set high. This means that all I/O pins will default to an input state, the level of which depends on the other connected circuitry and whether pull- high selections have been chosen.

  • Page 142 BC68F2130/BC68F2140/BC68F2150 Sub-1GHz RF Transmitter Flash MCU with OCDS LRR [m] Rotate Data Memory right Description The contents of the specified Data Memory are rotated right by 1 bit with bit 0 rotated into bit 7. Operation [m].i ← [m].(i+1); (i=0~6) [m].7 ←...
  • Page 143 BC68F2130/BC68F2140/BC68F2150 Sub-1GHz RF Transmitter Flash MCU with OCDS LSDZ [m] Skip if decrement Data Memory is 0 Description The contents of the specified Data Memory are first decremented by 1. If the result is 0 the following instruction is skipped. As this requires the insertion of a dummy instruction while the next instruction is fetched, it is a three cycle instruction.
  • Page 144 BC68F2130/BC68F2140/BC68F2150 Sub-1GHz RF Transmitter Flash MCU with OCDS LSNZ [m] Skip if Data Memory is not 0 Description If the content of the specified Data Memory is not 0, the following instruction is skipped. As this requires the insertion of a dummy instruction while the next instruction is fetched, it is a three cycle instruction.
  • Page 145 BC68F2130/BC68F2140/BC68F2150 Sub-1GHz RF Transmitter Flash MCU with OCDS LSZ [m].i Skip if bit i of Data Memory is 0 Description If bit i of the specified Data Memory is 0, the following instruction is skipped. As this requires the insertion of a dummy instruction while the next instruction is fetched, it is a three cycle instruction.
