u32CurrentAddress = Bzero_Sector8_start;
oReturnCheck = Fapi_issueBankEraseCommand((uint32 *)u32CurrentAddress, 0x001F);
// Wait until FSM is done with bank erase operation
while (Fapi_checkFsmForReady() != Fapi_Status_FsmReady)
{
//
// Initialize the Erase Pulses to zero after issuing max pulses
//
if(HWREG(FLASH0CTRL_BASE + FLASH_O_ACC_EP) > MAX_ERASE_PULSE)
{
EALLOW;
//
// Enable Flash Optimization
//
HWREG(FLASH0CTRL_BASE + FLASH_O_OPT) = OPT_ENABLE;
HWREG(FLASH0CTRL_BASE + FLASH_O_ERA_PUL) =
HWREG(FLASH0CTRL_BASE + FLASH_O_ERA_PUL) &
~(uint32_t)FLASH_ERA_PUL_MAX_ERA_PUL_M;
//
// Disable Flash Optimization
//
代码中使用driverlib模式操作寄存器。
其中用到的几个宏定义如下(位于文件flash_programming_f28003x.h中)：

#define FLASH0CTRL_BASE 0x0005F800U
#define FLASH0ECC_BASE 0x0005FB00U
//
// FMC Registers, Masks and Values
//
#define FLASH_O_ACC_EP 0x148U // Flash Accumulated Erase Pulses
#define FLASH_O_ERA_PUL 0x136U // Flash Max Erase Pulses
#define FLASH_O_OPT 0x144U // Flash Optimization
#define FLASH_ERA_PUL_MAX_ERA_PUL_M 0xFFFU // Flash Max Erase Pulses Mask
#define OPT_ENABLE 0x5U // Flash Optimization Enable
#define OPT_DISABLE 0x2U // Flash Optimization Disable
#define MAX_ERASE_PULSE 0x7D0U // Flash Max Erase Pulses
在28003x参考手册sprui33f 中FLASH0_CTRL_REGS定义如下：
参考手册中并没有偏移地址为以下几个地址的寄存器说明：
0x148U // Flash Accumulated Erase Pulses
0x136U // Flash Max Erase Pulses
0x144U // Flash Optimization
请问那里可以看到这几个寄存器的具体定义以及说明？
如果不使用driverlib，如何定义这些寄存器呢？（的f28003x_flash.h中没有定义这几个寄存器)
