Bit-banding support.

Functions

static uint8 bb_sram_get_bit(volatile void *address, uint32 bit)

Get a bit from an address in the SRAM bit-band region.

Return

bit’s value in address.

Parameters

• address -

  Address in the SRAM bit-band region to read from

• bit -

  Bit in address to read

static void bb_sram_set_bit(volatile void *address, uint32 bit, uint8 val)

Set a bit in an address in the SRAM bit-band region.

Parameters

• address -

  Address in the SRAM bit-band region to write to

• bit -

  Bit in address to write to

• val -

  Value to write for bit, either 0 or 1.

static uint8 bb_peri_get_bit(volatile void *address, uint32 bit)

Get a bit from an address in the peripheral bit-band region.

Return
