Table 8-1 Control Registers
1.
The ‘byte, bit’ means registers are controlled by both bit and byte manipulation instruction.
Caution) The R/W register except T1PDR and T3PDR are both can be byte and bit manipulated.
2.
The ‘byte’ means registers are controlled by only byte manipulation instruction. Do not use bit manipulation
instruction such as SET1, CLR1 etc. If bit manipulation instruction is used on these registers,
content of other seven bits are may varied to unwanted value.
*The mark of ‘-’ means this bit location is reserved.
