EC_AM_MODE
RW
R
0
This field specifies the clocking for the address
matching (I2C) or slave selection detection logic (SPI)
'0': Internally clocked mode
'1': Externally clocked mode
In internally clocked mode, the serial interface
protocols run off the SCB clock. In externally clocked
mode, the serial interface protocols run off the clock as
provided by the serial interface.
The clocking for the rest of the logic is determined by
CTRL.EC_OP_MODE.
Externally clocked mode is only used for synchronous
serial interface protocols (SPI and I2C) in slave mode.
In SPI mode, only Motorola submode (all Motorola
modes: 0, 1, 2, 3) is supported.
In UART mode this field should be '0'.

EC_OP_MODE
RW
R
0
This field specifies the clocking for the SCB block
'0': Internally clocked mode
'1': externally clocked mode
In internally clocked mode, the serial interface
protocols run off the SCB clock. In externally clocked
mode, the serial interface protocols run off the clock as
provided by the serial interface.
Externally clocked operation mode is only used for
synchronous serial interface protocols (SPI and I2C) in
slave mode AND EZ mode. In SPI mode, only
Motorola submode (all Motorola modes: 0, 1, 2, 3) is
supported. The maximum SPI slave, EZ mode bitrate
is 48 Mbps (transmission and IO delays outside the IP
will degrade the effective bitrate).
In UART mode this field should be '0'.
10
EZ_MODE
RW
R
0
Non EZ mode ('0') or EZ mode ('1').
In EZ mode, a meta protocol is applied to the serial
interface protocol. This meta protocol adds meaning to
the data frames transferred by the serial interface
protocol: a data frame can represent a memory
address, a write memory data element or a read
memory data element. EZ mode is only used for
synchronous serial interface protocols: SPI and I2C. In
SPI mode, only Motorola submode (all Motorola
modes: 0, 1, 2, 3) is supported and the transmitter
should use continuous data frames; i.e. data frames
not separated by slave deselection. This mode is only
applicable to slave functionality. In EZ mode, the slave
can read from and write to an addressable memory
structure of 32 bytes. In EZ mode, data frames should
8-bit in size and should be transmitted and received
with the Most Significant Bit (MSB) first.
In UART mode this field should be '0'.
