Using the HC9S08Rx MCU Family Analog Comparator
Low power oscillator capable of operating from crystal or resonator from
1 to 16 MHz
On-chip analog comparator with internal reference (ACMP)
–
–
Serial communications interface module (SCI)
Serial peripheral interface module (SPI)
2-channel, 16-bit timer/pulse width modulator (TPM) module with selectable
input capture, output compare, and edge-aligned or center-aligned PWM
capability on each channel.
Keyboard interrupt ports (KBI1 and KBI2) providing 12 keyboard interrupts
–
Carrier modulator timer (CMT) with dedicated infrared output (IRO) pin
–
–
–
Eight high-current pins (limited by maximum package dissipation)
Software selectable pull-ups on ports when used as input. Selection is on an
individual port bit basis.
During output mode, pull-ups are disengaged.
39 general-purpose input/output (I/O) pins, depending on package selection
Four packages available:
