20.3.13
The PSoC Memory Arbiter Read Address Register
(PMAx_RA) is used to set the beginning address for the
PMA channel. A PMAx_RA register address uses the same
physical register as the PMAx_WA register address. There-
fore, when the read address is changed, the write address is
also changed and the PMAx_WA and PMAx_RA registers
always return the same value when read. When a
PMAx_RA register is written, the address is stored and the
value of the corresponding SRAM address is loaded into the
channel's PMAx_DR. Therefore, this register must only be
written after valid data has been stored in SRAM for the
channel.
20.3.14
The USB Control Register 1 (USB_CR1) is used to config-
ure the internal regulator and the oscillator tuning capability.
Bit 2: BusActivity. The BusActivity bit is a "sticky" bit that
detects any non-idle USB event that has occurred on the
USB bus. After set to high by the SIE to indicate the bus
activity, this bit retains its logical high value until firmware
clears it. Writing a '0' to this bit clears it; writing a '1' pre-
serves its value. ‘0‘ is no activity. '1' is non-idle activity (D+ =
low) was detected since the last time the bit was cleared.

Bits 7 to 0: Address[7:0]. The value returned when this
register is read depends on whether the PMA channel is
being used by the USB SIE or by the M8C. In the USB SIE
case, this register always returns the beginning SRAM
address for the PMA channel. In the M8C case, this register
always returns the next SRAM address that is used by the
PMA channel, if a byte is read from the channel's data regis-
ter (PMAx_DR) by the M8C.

Bit 1: EnableLock. Set this bit to turn on the automatic fre-
quency locking of the internal oscillator to USB traffic.
Unless an external clock is being provided, this bit must
remain set for proper USB operation. ‘0‘ is locking disabled.
'1' is locking enabled.
Bit 0: RegEnable. This bit controls the operation of the
internal USB regulator. For applications with device supply
voltages in the 5V range, set this bit high to enable the inter-
nal regulator. For device supply voltages in the 3.3V range,
clear this bit to connect the transceiver directly to the supply.
‘0‘ is passthrough mode. Use for Vdd = 3.3V range. '1' is
regulating mode. Use for Vdd = 5V range.
