GPO Data Registers (Read/Write)
BIT
7:2
15:11
0
FIELD NAME
GPODAT[5:0]
GPODAT[10:6]
GPODAT[11]
DESCRIPTION
Data transmitted through GPO ports 0 to 11
• Data written by the host to be transmitted through the GPO-configured ports
• For a given port i (0≤i≤11):
• GPIDAT[i] = 0: A logic zero level is transmitted through GPO port i
• GPIDAT[i] = 1: A logic one level is transmitted through GPO port i
DAC Preset Data Registers (Read/Write)
BIT
FIELD NAME
DESCRIPTION
DAC preset data register 1 and 2
11:0 DACPRSTDAT1[11:0] _{• DAC data used by all ports configured in a DAC-related mode (1, 3, 4, 5, 6, and 10)}
11:0 DACPRSTDAT2[11:0] _{• Writing to these registers does not alter the contents of the DAC data registers}
Temperature Monitor Configuration Register (Read/Write)
BIT
FIELD NAME
DESCRIPTION
Number of samples averaged for calculating the internal temperature
• 00: 4 samples
1:0
TMPINTMONCFG[1:0] ^{• 01: 8 samples}
• 10: 16 samples
• 11: 32 samples
Number of samples averaged for calculating the 1st external temperature
• 00: 4 samples
3:2
TMPEXT1MONCFG[1:0] ^{• 01: 8 samples}
• 10: 16 samples
• 11: 32 samples
Number of samples averaged for calculating the 2nd external temperature

Internal Temperature Monitor High Threshold Register (Read/Write)
BIT
FIELD NAME
DESCRIPTION
Internal temperature monitor high threshold
11:0
TMPINTHI[11:0]
• Maximum temperature value beyond which TMPINT[2] is asserted.
• This value is represented in two’s complement; one LSB represents 0.125°C.
