Notes 1.
This is the pin status when the N-Wire function has been set to use prohibit status via a setting for the
NWIREEN pin.
2.
When SyncFlash memory has been selected as the boot ROM, this pin can be used as the GPIO pin.
3.
The registers in the GIU can be used to set 1, 0, or high impedance.
4.
See the other pin names and alternate-function pin names.
5.
The GPIO19 and GPIO17 signals are sampled as CLKSEL(1:0) when the RTCRST# signal has
changed to high level in order to set the frequency of the CPU core’s pipeline reference clock
(AClock).
Caution
After an RTC reset, the GPIO pins are set in the input direction and input disable status is set.
Input enable status can be set by software after an RTC reset. Accordingly, there is no need to
externally add elements such as pull-up or pull-down resistors for unused GPIO pins in order to
determine the signal status. However, GPIO(61:54), which are shared with A(22:15), function as
GPIO pins only when SyncFlash memory has been selected. The status of output pins in
Hibernate mode can be specified by using software to enter the required settings in internal
registers in advance.
Remarks 1.
0: Low level, 1: High level, Hi-Z: High impedance
2.
When a pin has high impedance, the buffer’s input enable setting is OFF. Leakage current will not
occur even when an intermediate level is applied.
