PL030_RTC component

This section describes the PL030_RTC component.

PL030_RTC - about

ARM PrimeCell Real Time Clock (PL030). This model is written in LISA+.

PL030_RTC contains the following CADI targets:

  • PL030_RTC

PL030_RTC contains the following MTI components:

PL030_RTC - ports

This section describes the ports.

Table 4-130 PL030_RTC ports

Name Protocol Type Description
pvbus PVBus Slave Slave port for connection to PV bus master/decoder
intr Signal Master Interrupt signaling
clock ClockSignal Slave Clock input, typically 1MHz, driving master count rate

PL030_RTC - registers

This section describes the ports.

Table 4-131 PL030_RTC registers

Name Offset Access Description
RTCDR 0x00 Read only Data register
RTCMR 0x04 Read/write Match register
RTCSTAT 0x08 Read only Interrupt status register
RTCEOI 0x08 Write only Interrupt clear register
RTCLR 0x0C Read/write Counter load register
RTCCR 0x10 Rad/write Counter register

PL030_RTC - verification and testing

This component passes tests as part of the VE example system by using VE test suites and by booting operating systems.

PL030_RTC - performance

This component has no impact on the performance of a PV system when idle or counting down. The component only executes code when the counter expires or during bus accesses.
