The Timer 0–2 High and Low Byte (TxH and TxL) registers
contain the current 16-bit timer count value. When the timer is enabled, a read from TxH
causes the value in TxL to be stored in a temporary holding register. A read from TxL
always returns this temporary register when the timers are enabled. When the timer is
disabled, reading from the TxL reads the register directly.
Writing to the Timer High and Low Byte registers when the timer is enabled is not
recommended. There are no temporary holding registers available for write operations, so
simultaneous 16-bit writes are not possible. If either the Timer High or Low Byte registers
are written during counting, the 8-bit written 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 2 bytes, {TH[7:0], TL[7:0]}, contain the current 16-bit timer count value.
