It is left to the discretion of the software 70 architect to decide how and when the semaphores are used and how they are allocated. Existing hardware does not have to be 71 72 modified for this type of cooperative sharing, and the use of semaphores is exclusively within the software domain. 73 */ 74 75 /** 76 * @ingroup sema_registers 77 * Structure type to access the SEMA Registers. 78 */ 79 typedef struct { 80 __IO uint32_t semaphores[8]; /**< <tt>\b 0x000:</tt> SEMA SEMAPHORES Register */ 81 __R uint32_t rsv_0x20_0xff[56]; 82 __IO uint32_t status; /**< <tt>\b 0x100:</tt> SEMA STATUS Register */ 83 } mxc_sema_regs_t; 84 85 /* Register offsets for module SEMA */ 86 /** 87 * @ingroup sema_registers 88 * @defgroup SEMA_Register_Offsets Register Offsets 89 * @brief SEMA Peripheral Register Offsets from the SEMA Base Peripheral Address. 90 * @{ 91 */ 92 #define MXC_R_SEMA_SEMAPHORES ((uint32_t)0x00000000UL) /**< Offset from SEMA Base Address: <tt> 0x0000</tt> */ 93 #define MXC_R_SEMA_STATUS ((uint32_t)0x00000100UL) /**< Offset from SEMA Base Address: <tt> 0x0100</tt> */ 94 /**@} end of group sema_registers */ 95 96 /** 97 * @ingroup sema_registers 98 * @defgroup SEMA_SEMAPHORES SEMA_SEMAPHORES 99 * @brief Read to test and set, returns prior value.
