• Manufacturer Part Number: HT48R10A-1_09
• Description: I/O Type 8-Bit MCU
• Manufacturer: HOLTEK [Holtek Semiconductor Inc]

The states of the registers is summarized in the table.
Note:
Timer/Event Counter
A timer/event counters (TMR) is implemented in the
microcontroller. The timer/event counter contains an
8-bit programmable count-up counter and the clock may
come from an external source or from the system clock
or RTC.
Using the internal clock sources, there are 2 reference

time-bases for timer/event counter. The internal clock
source can be selected as coming from (can always be
optioned) or f
Int. RC+RTC mode) by options. Using external clock in-
put allows the user to count external events, measure
time internals or pulse widths, or generate an accurate
time base. While using the internal clock allows the user
to generate an accurate time base.
