自己顶一下,从CSR8670手册中查到原因:
If wake up of CSR8670 BGA is required via the VCHG pin, then the operation of PIO[9] is NC and
should be left unconnected. Otherwise, configuration of PIO[9] as a PIO is by setting
PSKEY_VCHG_REROUTE_INTERNALLY_VIA_PIO to 0xffff, for more information contact CSR.
If wake up of CSR8670 BGA is required via the VREGENABLE pin, then the operation of PIO[8] is
NC and should be left unconnected. Otherwise, configuration of PIO[8] as a PIO is by setting
PSKEY_VREG_EN_REROUTE_INTERNALLY_VIA_PIO to 0xffff, for more information contact
CSR.
