The following sections provide a detailed description of the MC13202 functionality including the
operating modes and Serial Peripheral Interface (SPI).
6.1
The MC13202 has a number of operational modes that allow for low-current operation. Transition from
the Off to Idle mode occurs when RST is negated. Once in Idle, the SPI is active and is used to control the
IC. Transition to Hibernate and Doze modes is enabled via the SPI. These modes are summarized, along
with the transition times, in
Characteristics.
6.2
The host microcontroller directs the MC13202, checks its status, and reads/writes data to the device
through the 4-wire SPI port. The transceiver operates as a SPI slave device only. A transaction between
the host and the MC13202 occurs as multiple 8-bit bursts on the SPI. The SPI signals are:

Serial Peripheral Interface (SPI)
All IC functions Off, Leakage only. RST asserted. Digital outputs are tri-stated
including IRQ
retained.
Crystal Reference Oscillator On but CLKO output available only if Register 7, Bit 9 =
1 for frequencies of 1 MHz or less. (SPI not functional.) Responds to ATTN and can
be programmed to enter Idle Mode through an internal timer comparator.
Crystal Reference Oscillator On with CLKO output available. SPI active.
Crystal Reference Oscillator On. Receiver On.
Crystal Reference Oscillator On. Transmitter On.
For Freescale microcontrollers, the SPI clock format is the clock phase
control bit CPHA = 0 and the clock polarity control bit CPOL = 0.
