TMP94C241C
A reset initializes <TR0/2DE> to “0”, disabling the double-buffer. When using the
double-buffer, first write data to the timer register and set <TR0/2DE> to “1”, then
write the following data to the register buffer.
Figure 3.8.3 Timer Register 0/2/4/6 Configuration
Note:
The timer register and register buffer are allocated to the same address in memory.
When <TR0/2DE> is set to “0”, the same value is written to both the register buffer and the timer
register. When <TR0/2DE> is set to “1”, the value is written to the register buffer only.
The timer register TREG0, TREG1, TREG2, TREG3 are write only; cannot read data from them.
As the initial values are undefined, when using an 8-bit timer, be sure to write values.
