DATA SHEET
DESCRIPTION
The
μ
PD6125A and 6126A are 4-bit single-chip microcontrollers for infrared remote controllers for TVs, VCRs,
stereos, cassette decks, air conditioners, etc.
These microcontrollers consist of ROM, RAM, a 4-bit parallel-processing ALU, a programmable timer, key input/
output ports, and transmit output ports. Functioning is controlled in software.
Caution To use the NEC transmission format, ask NEC to supply the custom code.
The mask option (PLA data) setting of
μ
PD6125A,

When a register is used as the operand of a branch instruction, do not use R
0
