Digital ground.
UART Receive Data (in), or GPIO27
This signal can be used for device low-power mode, it will turn off or disable
external powers to the peripheral in suspend mode. Once USB power is
resumed, external power can be enabled again
GPIO25, or IRQ1 (in) interrupts the SL11R processor
IRQ0 (in) interrupts the SL11R processor or PWM.
See the PWM Control register set-up for more information

DMA Request Enable. DREQ indicates that SL11R is ready to accept or send
data from/to an external device. DREQ along with nCS, nWRITE and nREAD
bits are the DMA handshake signals for the main SDATA port, or GPIO20.
ADDR =1, Read/Write data from the INBUF/OUTBUFF, ADDR=0 read data
from the STATUS register, or GPIO19
+3.3 VDC Supply
CS (in) Active LOW, Selects the bidirectional SDATA Port, or GPIO18
Active input LOW signal used to indicate write data transfers to the general
bidirectional SD15-0 Data Port. Signal is driven high for read transfers to the
SL11R, or GPIO17
