Table 58. Timer 0 High Byte Register (T0H)
Table 59. Timer 0 Low Byte Register (T0L)
causes the value in T0L to be stored in a temporary holding register. A Read from T0L
always returns this temporary register when the timer is enabled. When the timer is dis-
abled, Reads from the T0L are direct from this temporary register.
If either the Timer High or Low Byte registers are written during counting, the 8-bit writ-
ten value is placed in the counter (High or Low Byte) at the next clock edge. The counter
continues counting from the new value.
TH and TL—Timer High and Low Bytes
These two bytes, {TH[7:0], TL[7:0]}, contain the current 16-bit timer count value.
Writing to the Timer High and Low Byte registers while the timer is enabled is not rec-
ommended. There are no temporary holding registers available for Write operations;
therefore, simultaneous 16-bit Writes are not possible.
