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, {TMRH[7:0], TMRL[7:0]}, contain the current 16-bit timer count value.
The Timer 0-3 Reload High and Low Byte (TxRH and TxRL) registers (Tables 40 and 41)
store a 16-bit reload value, {TRH[7:0], TRL[7:0]}. Values written to the Timer 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.
In Compare mode, the Timer Reload High and Low Byte registers store the 16-bit Com-
pare value.
In single-byte DMA transactions to the Timer Reload High Byte register, the temporary
holding register is bypassed and the value is written directly to the register. If the DMA is
