DEVICE REGISTER ADDRESSING
addresses (D[14:10]) and their impact on device operation.
ADDRESS XX000 — STATUS REGISTER
(STATR_S)
the various configuration register contents without disrupting
the device operation or the register contents. The register bits
D[4:0] determine the content of the first sixteen bits of SO
data. In addition to the device status, this feature provides the
ability to read the content of the PWMR_s, CONFR0_s,
CONFR1_s, OCR_s, GCR and CALR registers (Refer to the
section entitled
Return Data) on page
ADDRESS A
REGISTER (PWMR_S)
of corresponding output through the SPI. Each output “s” is
independently selected for configuration based on the state
of the D14 : D13 bits
