Table 37-8. RTP Global Control Register (RTPGLBCTRL) Field Descriptions
Bit Field Value Description
31-25 Reserved 0 Reads return 0. Writes have no effect.
24 TEST By setting the bit, the FIFO RAM will be mapped into the SYSTEM Peripheral frame starting at
address 0xFFF83000. Each FIFO starts at a 1-k boundary. Each FIFO entry is aligned to a 128-
bit boundary. See Table 37-9 for a listing of the FIFOs and their corresponding addresses.
Read:
0 FIFO RAM is not accessible in the memory-map.
1 FIFO RAM is mapped to address FFF8 3000h.
Write in Privilege:
0 Disables mapping of the FIFO RAM.
1 Enables mapping of the FIFO RAM into address FFF8 3000h.
18-16 PRESCALER The prescaler divides HCLK down to the desired RTPCLK frequency. The maximum RTPCLK
frequency specified in the device datasheet must not be exceeded. No dynamic change of
RTPCLK is supported. The module should be switched off by the ON/OFF bits in this register
before changing the prescaler.
User and privilege mode read, privilege mode write:
0 Prescaler is HCLK/1.
1h Prescaler is HCLK/2.
2h Prescaler is HCLK/3.
3h Prescaler is HCLK/4.
4h Prescaler is HCLK/5.
5h Prescaler is HCLK/6.
6h Prescaler is HCLK/7.
7h Prescaler is HCLK/8.
15-14 Reserved 0 Reads return 0. Writes have no effect.
13-12 DDM_WIDTH Direct data mode word size width. This bit field configures the number of bits that will be
transmitted in Direct Data Mode.
User and privilege mode read, privilege mode write:
0 Word size width is 8 bits.
1h Word size width is 16 bits.
2h Word size width is 32 bits.
3h Reserved
