The Timer 0–1 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 dis-
abled, reads from the TxL reads the register directly.
Writing to the Timer High and Low Byte registers while the timer is enabled is not recom-
mended. There are no temporary holding registers available for write operations, so simul-
taneous 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
The Timer 0–1 Reload High and Low Byte (TxRH and TxRL) registers
Table
Reload High Byte register are stored in a temporary holding register. When a write to the
Timer Reload Low Byte register occurs, the temporary holding register value is written to
the Timer High Byte register. This operation allows simultaneous updates of the 16-bit
Timer Reload value.
