General Description
The HT86030/HT86070 series are 8-bit high perfor-
mance microcontroller with voice synthesizer and tone
generator. The HT86030/HT86070 is designed for ap-
plications on multiple I/Os with sound effects, such as
voice and melody. It can provide various sampling rates
and beats, tone levels, tempos for speech synthesizer
and melody generator. It has a single built-in high qual-
ity, D/A output. There is an external interrupt which can
be triggered with falling edge pulse or falling/rising edge
pulse.
The HT86030/HT86070 is excellent for versatile voice
and sound effect product applications. The efficient
MCU instructions allow users to program the powerful
custom applications. The system frequency of
HT86030/HT86070 can be up to 8MHz under 2.4V and
include a HALT function to reduce power consumption.

Wake-up,
Pull-high
or None
Bidirectional 8-bit I/O port. Each bit can be configured as a wake-up input
by mask option. Software instructions determine the CMOS output or
Schmitt trigger input with or without pull-high resistor (mask option).
PB0~PB7 I/O
Pull-high
or None
Bidirectional 8-bit I/O port. Software instructions determine the CMOS
output or Schmitt trigger input (pull-high resistor depending on mask op-
tion).

falling edge trigger or falling/rising edge trigger by mask option. Falling
edge triggered active on a high to low transition. Rising edge triggered
active on a low to high transition.
OSC1
OSC2
OSC1 and OSC2 are connected to an RC network or a crystal (by mask
option) for the internal system clock. In the case of RC operation, OSC2
¾ RC or Crystal is the output terminal for 1/4 system clock.
The system clock may come from the crystal, the two pins cannot be
floating.

Indirect Addressing Register
Location 00H and 02H are indirect addressing registers
that are not physically implemented. Any read/write op-
eration of [00H] and [02H] accesses the RAM pointed to
by MP0 (01H) and MP1 (03H) respectively. Reading lo-
cation 00H or 02H indirectly returns the result 00H.
While, writing it indirectly leads to no operation.
The function of data movement between two indirect ad-
dressing registers is not supported. The memory pointer
registers, MP0 and MP1, are both 8-bit registers used to
access the RAM by combining the corresponding indi-
rect addressing registers.
Accumulator - ACC (05H)
The accumulator (ACC) is related to the ALU opera-
tions. It is also mapped to location 05H of the RAM and
is capable of operating with immediate data. The data
movement between two data memory locations must
pass through the ACC.
Arithmetic and Logic Unit - ALU
This circuit performs 8-bit arithmetic and logic opera-
tions and provides the following functions:
· Arithmetic operations (ADD, ADC, SUB, SBC, DAA)
· Logic operations (AND, OR, XOR, CPL)
· Rotation (RL, RR, RLC, RRC)
· Increment and Decrement (INC, DEC)
· Branch decision (SZ, SNZ, SIZ, SDZ etc)
Status Register - STATUS
This 8-bit STATUS register (0AH) consists of a zero flag
(Z), carry flag (C), auxiliary carry flag (AC), overflow flag
(OV), power down flag (PDF), watchdog time-out flag
(TO). It also records the status information and controls
the operation sequence.
Except the TO and PDF flags, bits in the status register
can be altered by instructions similar to other registers.
Data written into the status register does not alter the TO
or PDF flags. Operations related to the status register,
