Field Name (ID): Description
31
0b
RW
Mode (MOD):
•
•
0 = Normal SSP Mode
•
1 = Network Mode
30
0b
RW
Audio Clock Select (ACS):
•
•
0 = Clock selection is determined by the NCS and ECS bits
•
1 = Audio Clock ( and Audio Clock Divider) are used to create the SSP's serial clock
(SSPSCLK)
29
0b

Reserved (RSVD):
Reserved.

000b
RW
Frame Rate Divider Control (FRDC):
Value 0-7 indicates the number of time slots per
frame when in network mode (the actual number of time slots is FRDC+1, so 1 to 8 time
slots).
23
0b
RW
Transmit FIFO Under Run Interrupt Mask (TIM):
•
•
0 = TUR events will generate an SSP interrupt
•
1 = TUR events will not generate an SSP interrupt
22
0b
RW
Receive FIFO Over Run Interrupt Mask (RIM):
•
•
0 = ROR events will generate an SSP interrupt
•
1 = ROR events will not generate an SSP interrupt
21
0b
RW
Network Clock Select (NCS):
•
•
0 = Clock selection is determined by ECS bit
•
1 = Network clock is used to create the SSP's serial clock (SSPSCLK)
20
0b
RW
Extended Data Size Select (EDSS):
•
•
0 = A zero is prepended to the DSS value, which sets the DSS range from 4-16 bits
•
1 = A one is pre-appended to the DSS value which sets the DSS range from 17-32
bits
19:8
000h
RW
Serial Clock Rate (SCR):
Value (0 to 4095) used to generate transmission rate of SSP.
Serial bit rate = SSP clock/(SCR+1), where SCR is decimal integer.
7
0b
RW
Synchronous Serial Port Enable (SSE):
•
•
0 = SSP operation disabled
•
1 = SSP operation enabled
6
0b
RW
External Clock Select (ECS):
•
•
0 = On-chip clock used to produce the SSP's serial clock (SSPSCLK)
•
1 = SSPEXTCLK/GPIO pin is used to create the SSP's SSPCLK
5:4
00b
RW
Frame Format (FRF):
•
•
00 = Motorola Serial Peripheral Interface (SPI)
•
01 = Texas Instruments Synchronous Serial Protocol (SSP)
•
10 = National Semiconductor Microwire
•
11 = Programmable Serial Protocol (PSP)
3:0
0000b
RW
Data Size Select (DSS):
With EDSS as MSB, value+1 gives data size. Values 4 to 32
allowed.
