函数说明
◆ hal_sfc_regs_wait_ready()
| errcode_t hal_sfc_regs_wait_ready | ( | uint8_t | wip_bit | ) |
◆ sfc_port_fix_sr()
◆ sfc_port_read_sr()
| uint32_t sfc_port_read_sr | ( | uint32_t | cmd | ) |
读取状态寄存器的值。
- 参数
-
[in] cmd 命令字可以是：05H/35H/15H。 05H: 读 SR1 35H: 读 SR2 15H: 读 SR3
- 返回值
-
读取到的SR中的值。
◆ sfc_port_write_lock()
| uint32_t sfc_port_write_lock | ( | uint32_t | start_addr, |
| uint32_t | end_addr | ||
| ) |
SFC上锁，同时根据地址信息，放开对应区域的擦、写权限。
◆ sfc_port_write_sr()
| void sfc_port_write_sr | ( | bool | is_volatile, |
| uint8_t | cmd, | ||
| uint8_t | data | ||
| ) |
写状态寄存器。
- 参数
-
[in] is_volatile 是否是易失性写入。 True: 易失性写入, 掉电后配置丢失。 False: 非易失性写入, 掉电后配置不丢失。 [in] cmd 命令字可以是：01H/31H/11H。 01H: 写 SR1 31H: 写 SR2 11H: 写 SR3 [in] data 待写入的SR寄存器的数据。
- 返回值
-
ERRCODE_SUCC 成功。 Other 失败，参考 errcode_t 。
◆ sfc_port_write_unlock()
| void sfc_port_write_unlock | ( | uint32_t | lock_sts | ) |
SFC解锁。
