Note:
*T0EN : timer0 enable flag
T0EN = 1, load T0BF content (preload buffer data) into timer0 and enable timer0 start to down
count.
T0EN = 0, stop timer0 counting. User can get timer0 data by reading T0BF register. (LDA
T0BF)
* when T0EN=0, write data to T0BF(04H), data will be directly passed to timer0 counter.
T0F : timer0 underflow flag
T0F = 1, timer0 underflow;
T0F = 0, timer0 not underflow.
*T0CK : timer0 clock source option bit, need set to 0 in EU1010.
T0CK = 0, clock source from Fosc.
*There is no default data with T0CK bit, user should preset this bit after power on reset.

Note:
*Bit2~0 are timer0 clock source selection bits. They must follow the setting listed below. If the
bit2=1, it would be divided by 16 while bit1 and bit0 could be any data. When T0CK=1, don’t care
bit2~0 data.
