The RTC contains a low-power 32.768KHz RC oscillator which provides fast startup at 
first application of RTC power. It also supports an optional 32.768KHz crystal oscillator 
which can be substituted for the RC oscillator under software control. In normal 
operation, the RTC is always powered up. 

The standby programmable counter is 48-

bits and provides up to 272 years’ worth of 

standby duration. For the RTC_IO pin, the programmable embedded counter (32-bit) is 
provided to enable periodic wake-up of the remainder of the external system, and 
provide a 1.5 days’ max period. The RTC_IO pin can be configured as input (ALARM) or 
output (WAKE UP) pin. 

The RTC includes a Power-On Reset (POR) circuit, to eliminate the need for an external 
component. The RTC contains low-leakage non-volatile (battery-powered) RAM, to 
enable storage of data that needs to be preserved. It also includes a brown-out detector 
that can be disabled by SW. 

2.1.6.2. 

Real Time Clock Counter 

•

 

The Real Time Counter features: 

–

 

48-bit length (with absolute duration of 272 years). 

–

 

Low-power design. 

•

 

This counter is automatically reset by power-on-reset. 

•

 

This counter wraps around 

(returns to “all-0” once it has reached the 

highest possible “all-1” value). 

2.1.6.3. 

RTC I/O 

There is one (1) RTC I/O that can be used to control external devices, such as sensors 
or wake up the module based on external events or devices. 

2.1.7. 

GS2101M Peripherals 

2.1.7.1. 

SDIO Interface 

The SDIO interface is a full / high speed SDIO device (slave). The device supports SPI, 
1-bit SD and 4-bit SD bus mode. The SDIO block has an AHB interface, which allows the 
CPU to configure the operational registers residing inside the AHB Slave core. The CIS 
and CSA area is located inside the internal memory of CPU subsystem. The SDIO 
Registers (CCCR and FBR) are programmed by both the SD Host (through the SD Bus) 
and CPU (through the AHB bus) via Operational registers. The SDIO block implements 
the AHB master to initiate transfers to and from the system memory autonomously

. 

During the normal initialization and interrogation of the card by the SD Host, the card will 
identify itself as an SDIO device. The SD Host software will obtain the card information in a 
tuple (linked list) format and determine if that card’s I/O function(s) are acceptable to 
activate. If the Card is acceptable, it will be allowed to power up fully and start the I/O 
function(s) built into it. 

The SDIO interface implements Function 1 in addition to the default Function 0. All 
application data transfers are done through the Function 1 

The primary features of this interface are 

 

•

 

Meets SDIO card specification version 2.0. 

•

 

Conforms to AHB specification. 

•

 

Host clock rate variable between 0 and 40 MHz
