HT48R01/HT48R02/HT48R03
The internal timer/event counter interrupt is initialised by
setting the timer/event counter interrupt request flag
(TF; bit 5 of INTC), caused by a timer overflow. When
the interrupt is enabled, the stack is not full and the TF
bit is set, a subroutine call to location 08H will occur. The
related interrupt request flag,TF, will be reset and the
EMI bit cleared to disable further interrupts.
During the execution of an interrupt subroutine, other in-
terrupt acknowledgments are held until the ²RETI²
instruction is executed or the EMI bit and the related in-
terrupt control bit are set to 1 (of course, if the stack is
not full). To return from the interrupt subroutine, ²RET²
or ²RETI² may be invoked. RETI will set the EMI bit to en-
able an interrupt service, but RET will not.
Interrupts, occurring in the interval between the rising
edges of two consecutive T2 pulses, will be serviced on
the latter of the two T2 pulses, if the corresponding inter-
rupts are enabled. In the case of simultaneous requests
the following table shows the priority that is applied.
These can be masked by resetting the EMI bit.

Once the interrupt request flags (T0F/ T1F, EIF) are set,
they will remain in the INTC register until the interrupts
are serviced or cleared by a software instruction. It is
recommended that a program does not use the ²CALL
subroutine² within the interrupt subroutine. Interrupts
often occur in an unpredictable manner or need to be
serviced immediately in some applications. If only one
stack is left and enabling the interrupt is not well con-
trolled, the original control sequence will be damaged
once the ²CALL² operates in the interrupt subroutine.
Oscillator Configuration
There are 4 different oscillator modes implemented in
the microcontroller, which are selected by configuration
options. All of them are designed for system clocks,
namely the external RC oscillator (ERC), external crys-
tal oscillator (ECRY), internal RC oscillator with I/O(IRC)
and internal RC oscillator with RTC OSC (IRC+RTC).
No matter what oscillator type is selected, the signal
provides the system clock. The Power-down mode
stops the system oscillator, except for the RTC oscilla-
tor, and resists external signals to conserve power.
