#define PERIPHS_IO_MUX_FUNC 0x13
#define PERIPHS_IO_MUX_FUNC_S 4
#define PERIPHS_IO_MUX_PULLUP BIT7
#define PERIPHS_IO_MUX_PULLDWN BIT6
#define PERIPHS_IO_MUX_SLEEP_PULLUP BIT3
#define PERIPHS_IO_MUX_SLEEP_PULLDWN BIT2
#define PERIPHS_IO_MUX_SLEEP_OE BIT1
#define PERIPHS_IO_MUX_OE BIT0

#define PIN_PULLUP_DIS(PIN_NAME) CLEAR_PERI_REG_MASK(PIN_NAME, PERIPHS_IO_MUX_PULLUP)
#define PIN_PULLUP_EN(PIN_NAME) SET_PERI_REG_MASK(PIN_NAME, PERIPHS_IO_MUX_PULLUP)

因此我理解是可以设置deep sleep下的输出状态的，但试着设置了一下，没有作用，能帮忙解答正确的设置流程吗？
