GP Timer Enable (TIMER_EN). When a one is written to this bit the GP
Timer is put into the run state. When cleared, the GP Timer is halted. On
the 1 to 0 transition of this bit the GPT_LOAD field will be preset to FFFFh.
Reserved
General Purpose Timer Pre-Load (GPT_LOAD). This value is pre-loaded
into the GP-Timer.
GPO Data 3-4 (GPODn). The value written is reflected on GPOn.
GPIO Data 0-2 (GPIODn). When enabled as an output, the value written is
reflected on GPIOn. When read, GPIOn reflects the current state of the
corresponding GPIO pin.
GPO3 – bit 3
GPO4 – bit 4
GPIO0 – bit 0
GPIO1 – bit 1
GPIO2 – bit 2
GPT_CFG-General Purpose Timer Configuration Register
This register configures the General Purpose timer. The GP Timer can be configured to generate host
interrupts at intervals defined in this register.
