3 / 96 page Document Number: 002-05091 Rev.*B Page 3 of 96 S6E1A Series Watch Counter The Watch Counter wakes up the microcontroller from the low power consumption mode. The clock source can be selected from the main clock, the sub clock, the built-in high-speed CR clock or the built-in low-speed CR clock. Interval timer: up to 64 s (sub clock: 32.768 kHz) External Interrupt Controller Unit Up to 8 external interrupt input pins Non-maskable interrupt (NMI) input pin: 1 Watchdog Timer (2 channels) The watchdog timer generates an interrupt or a reset when the counter reaches a time-out value. This series consists of two different watchdogs, "hardware" watchdog and "software" watchdog. The "hardware" watchdog timer is clocked by the built-in low-speed CR oscillator. Therefore, the "hardware" watchdog is active in any low-power consumption modes except RTC mode and STOP mode. Clock and Reset Clocks A clock can be selected from five clock sources (two external oscillators, two built-in CR oscillator, and main PLL). Main clock : 4 MHz to 40MHz Sub clock : 32.768 kHz Built-in high-speed CR clock : 4 MHz Built-in low-speed CR clock : 100 kHz Main PLL clock Resets Reset request from the INITX pin Power on reset Software reset Watchdog timer reset Low-voltage detection reset Clock supervisor reset Clock Supervisor (CSV) The Clock Supervisor monitors the failure of external clocks with a clock generated by a built-in CR oscillator. If an external clock failure (clock stop) is detected, a reset is asserted. If an external frequency anomaly is detected, an interrupt or a reset is asserted. Low-voltage Detector (LVD) This series monitors the voltage on the VCC pin with a 2-stage mechanism. When the voltage falls below a designated voltage, the Low-voltage Detector generates an interrupt or a reset. LVD1: error reporting via an interrupt LVD2: auto-reset operation Low Power Consumption Mode This series has four low power consumption modes. SLEEP TIMER RTC STOP Peripheral Clock Gating The system can reduce the current consumption of the total system with gating the operation clocks of peripheral functions not used. Debug Serial Wire Debug Port (SW-DP) Micro Trace Buffer (MTB) Unique ID A 41-bit unique value of the device has been set. Power Supply Wide voltage range: VCC = 2.7 V to 5.5 V |
