PCMR data register (PCMRD)
Addr=5Ch; reset value=00h
Addr=5Dh; reset value=00h
Read-only
Table 63.
Table 64.
This register is used to read transmit PCM data via the MCU interface. Reading this register
the IPCM interrupt (if generated only by reading access) is automatically cleared.
In A/μ law only the first 8 bit are used. In linear code option both registers must be read, first
the LSB and after the MSB.
PCM control register (PCMCTRL)
Addr= 5Eh; reset value=00h
Read-only

PMW = 1: Data is not written every FS while writing PCM access data is enabled.
POW = 1: Data is not read every FS while reading PCM access data is enabled.
WRD = 1: Device is waiting for PCM data insertion in PCMWD register. The bit is reset
after writing at least one byte.
RRD = 1: Data are available on PCMRD register. The bit is reset after reading the two
bytes of the register (first the LSB and after the MSB).
