    SH66L10A 5. System Clock and Oscillator The oscillator generates the basic clock pulses that provide the system clock to supply CPU and on-chip peripherals. System clock f 5.1. Instruction Cycle Time: (1) 4/32.768kHz (≈ 122µs) for 32.768kHz oscillator. (2) 4/131 kHz (≈ 30.53µs) for 131kHz oscillator.
  • Page 9 SH66L10A 6. I/O Port The MCU provides 16 bi-directional I/O ports. The PORT data is put in register $08 - $0B. The PORT control register ($1B - $1E) controls the PORT as input or output. Each I/O port has an internal pull-high resistor, which is controlled by PPULL of $15 and the data of the PORT, when the PORT is used as input.
