related interrupt request flag (T1F) will be reset and the
EMI bit cleared to disable further interrupts.
The play interrupt is initialized by setting the play
interrupt request flag (bit 4 of INTC1), caused by a play
datavalid.Whentheinterruptisenabled,thestackisnot
full and the PLAYF is set, a subroutine call to location
10H will occur. The related interrupt request flag
(PLAYF) will be reset and the EMI bit cleared to disable
further interrupts. If PLAY_MODE (bit 3 of MODE_CTRL
register) is set to 1 , the play interrupt frequency will
change to 8KHz, otherwise the interrupt frequency is
48kHz.
The serial interface interrupt is indicated by the interrupt
flag (SIF; bit 5 of INTC1), that is generated by the
reception or transfer of a complete 8-bits of data
between the HT82A832R and the external device. The
serial interface interrupt is controlled by setting the
Serial interface interrupt control bit (ESII; bit 1 of
INTC1). After the interrupt is enabled (by setting SBEN;
bit4ofSBCR),andthestackisnotfullandtheSIFisset,
a subroutine call to location 14H occurs.
The record interrupt is initialized by setting the record
interrupt request flag (bit 6 of INTC1), caused by a
record data valid. When the interrupt is enabled, the
stack is not full and RECF is set, a subroutine call to
location18Hwilloccur.Therelatedinterruptrequestflag
(RECF) will be reset and the EMI bit cleared to disable
further interrupts. If ADC powered down (AD_ENB =1)
or USB clock disabled (USBCKEN=0), the record
interrupt will be disabled.
During the execution of an interrupt subroutine, other
interrupt acknowledge signals are held until the RETI
instruction is executed or the EMI bit and the related
interrupt control bit are set to 1 (if the stack is not full). To
return from the interrupt subroutine, RET or RETI
may be invoked. RETI will set the EMI bit to enable 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
interrupts are enabled. In the case of simultaneous
requests the following table shows the priority that is
applied.ThesecanbemaskedbyresettingtheEMIbit.

It is recommended that a program does not use the
CALL 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 controlled, the original control sequence will be
within the interrupt subroutine.
