Device Overview S12XS Family
1.2.3.8
PE7 is a general-purpose input or output pin. ECLKX2 is a clock output of twice the internal bus
frequency. The XCLKS is an input signal which controls whether a crystal in combination with the internal
loop controlled Pierce oscillator is used or whether full swing Pierce oscillator/external clock circuitry is
used (refer to Section 1.10 Oscillator Configuration). An internal pull-up is enabled during reset.
1.2.3.9
PE[6:5] are a general-purpose input or output pins.
1.2.3.10
PE4 is a general-purpose input or output pin. It can be configured to output the internal bus clock ECLK.
ECLK can be used as a timing reference. The ECLK output has a programmable prescaler.
1.2.3.11
PE[3:2] are a general-purpose input or output pins.
1.2.3.12
PE1 is a general-purpose input pin and the maskable interrupt request input that provides a means of
applying asynchronous interrupt requests. This will wake up the MCU from stop or wait mode.
1.2.3.13
PE0 is a general-purpose input pin and the non-maskable interrupt request input that provides a means of
applying asynchronous interrupt requests. This will wake up the MCU from stop or wait mode. The XIRQ
interrupt is level sensitive and active low. As XIRQ is level sensitive, while this pin is low the MCU will
not enter STOP mode.
1.2.3.14
PH[7:0] are a general-purpose input or output pins. They can be configured as keypad wakeup inputs.
1.2.3.15
PJ[7:6] are a general-purpose input or output pins. They can be configured as keypad wakeup inputs.
1.2.3.16
PJ[1:0] are a general-purpose input or output pins. They can be configured as keypad wakeup inputs.
1.2.3.17
PK[7,5:0] are a general-purpose input or output pins.
