Note:
24.2.7
PSELA is a 16-bit readable/writable register that has two purposes.
Bit 0 (RTCSEL1) selects a frequency for the low-frequency clock source that is used in the
Bluetooth interface (BT). When a 32.000kHz clock is selected, the clock is input to the BT. When
32.768-kHz clock is selected, the clock is converted into a pseudo 32.000kHz clock by the
frequency conversion circuit. For details, refer to section 21, Bluetooth Interface (BT).
Bits 1 to 8 select the function for a pin multiplexed with two or more other functions. When one of
the other functions are used, the corresponding bit in the PSELA should be specified before the
other function is specified by the port control register.
Setting example: To use IRQOUT function in the PTE6/RDI_CTRL2/IRQOUT pin
1. Write 1 to the PSA8 bit in the PSELA register.
2. Set the PE6MD1 and PE6MD0 bits in the port E control register (PECR) to (0.0) (other
