4.9 Calendar
The calendar module provides date and time information. It works on the 32.768 KHz oscillator with independent
power supply. In addition to provide timing data, alarm interrupt is generated and it is also used to power-up the
baseband core by sending wakeup signal.
Independent power supply.
Counters for second, minute, hour, day, month, year and day of week.
Maxim day of each month stored in module, leap year supported.
Alarm generate, wakeup triggered by alarm. Alarm IRQ.
Periodical IRQ for certain intervals
4.10 IR Receiver
The IR receiver module performs serial-to-parallel conversion on received data from a peripheral device. It supports
NEC, RC-5 and Philips 9012 mode.
Support 3 IR modes, NEC, RC-5 and Philips 9012
Store data code and user code
Support data code and user code verify
Enable interrupt when data received
Configurable frame time, bit time, high-time and low-time
4.11 SPI Master
This module is a master interface for a synchronous serial link, it can be configured to be compatible with Motorola SPI
or to comply with some various synchronous serial protocols.
Multiple chip selects and selectable data input.
Programmable clock polarity.
Programmable data frame size (from 4 to 32 bits).
Programmable delay options (time between CS, clocks and data).
Received pattern matching before filling RX FIFO (SD-MMC read block feature)
Transmit zero when TX FIFO empty (for generating dummy data during pattern matching read)
Direct pin control to force value to 0, 1 or input.
Special read mode with output enable control of the DO pin (selected input should be multiplexed with DO pin to
use this feature).
4.12 Timer
There are three different timers.
1 24-bit decremental timer for OS, ticks of 16384Hz.
