20.7 Registers
20.7.4 16-bit Reload Timer Reload Register
(Upper/Lower) ch. n (TMRLRHn/TMRLRLn)
The 16-bit reload timer reload register (upper/lower) ch. n (TMRLRHn/TMRLRLn)
sets the reload value for the 16-bit downcounter. The value written to this
register is reloaded to the 16-bit downcounter for downcounting.
â–  Register Configuration
â–  Register Functions
The 16-bit reload timer reload register ch. n sets the reload value to be reloaded to the 16-bit
downcounter.
The value set to the 16-bit reload timer reload register ch. n is reloaded to the 16-bit
downcounter for downcounting when the 16-bit reload timer starts or when an underflow
occurs. In addition, the value of this register can be modified during the counting operation of
the 16-bit reload timer.
Notes:
• A value can be written to this register even during the counting operation of the 16-bit
reload timer. To write a value to this register, use a word transfer instruction, or write
the upper byte of this register first and then its lower byte. The 16-bit reload timer
reload register ch. n has a circuit configured so that the upper byte value becomes
valid when a value is written to the lower byte.
• This register is write-only and located at the same address as the 16-bit reload timer
timer register ch. n. Therefore, a read access to this register becomes a read access
to the 16-bit reload timer timer register ch. n.
