General Description
The device is an 8-bit high performance RISC-like
microcontroller designed for multiple I/O product appli-
cations. It is particularly suitable for use in products
such as washing machine controllers and home appli-
ances. A HALT feature is included to reduce power con-
sumption.

pull-high resistor (determined by pull-high option: port option) or

Once a PB line is selected as an A/D input (by using software
control), the I/O function and pull-high resistor are disabled auto-
matically.

CMOS output or Schmitt trigger input with or without pull-high resis-
tor (determined by pull-high options: bit option). The PFD, TMR and
INT are pin-shared with PA3, PA4 and PA5, respectively. Once
the I2C BUS function is used, the internal registers related to PA6
and PA7 can not be used.
