There are some undefined bits in the registers. The values in these bits are unpredicted. These bits are not allowed to use. We use the symbol “-” in the spec to recognize them. A fixed value must be write in some specific unused bits by software or some unpredicted wrong will occur These bits are as below: Register Register PAGE R7 1 RA 2 RD 0 RE 0 IOC6 1 IOC8 0 IOC8 1 IOCA 1 IOCB 0 IOCC 0 IOCC 1 IOCC 1 IOCE 0 IOCF 0 Bit 1 7 5~6 1~3 7 1~7 1~7 3,6 0~7 4~7 0 3~7 0~3 6~7 Default value Initial Setting value (by user software) 0 0 X 1 X 0 0 0 0 0 1 0 0 0 X 0 1 0 1 0 X 1 X 0 0 0 0 0 Effect RAM access will error Un-expect error Power consumption increase Un-expect error LCD display error Power consumption increase Power consumption increase Power consumption increase Power consumption increase Power consumption increase AD function will error Un-expect error Un-expect error Un-expect error 2. You will see some names for the register bits definitions. Some name will be appear very frequently in the whole spec. The following describes the meaning for the register’s definitions such as bit type, bit name, bit number and so on. RA PAGE0 7 RAB7 R/W -0 Bit type Bit name Bit number Register name and its page 6 RAB6 R/W -0 read/write (default value=0) 5 BAB5 R-1 4 RAB4 R/W -1 read/write (default value=1) 3 - 2 RAB2 R 1 RAB1 R-0 0 RAB0 R/W read/write (w/o default value) read only (w/o default value) (undefined) not allowed to use read only (default value=1) read only (default value=0) 3. Always set IOCC PAGE1 bit 0 = 1 otherwise partial ADC function cannot be used. 4. Please do not switch MCU operation mode from normal mode to sleep mode directly. Before into sleep mode, please switch MCU to green mode. 5. While switching main clock (regardless of high freq to low freq or on the other hand), adding 6 instructions delay (NOP) is required. 6. Offset voltage will effect ADC’s result, please refer to figure 20 to detail. __________________________________________________________________________________________________________________________________________________________________ * This specification is subject to be changed without notice. 1 12/14/2004 (V1.4) EM785830AD 8-bit Micro-controller I.
