Reserved HSPCLK
R-0 R/W-001
LEGEND: R/W = Read/Write; R = Read only; - n = value after reset
Table 3-5. High-Speed Peripheral Clock Prescaler (HISPCP) Field Descriptions
Bits Field Value Description
(1)
15-3 Reserved Reserved
2-0 HSPCLK These bits configure the high-speed peripheral clock (HSPCLK) rate relative to SYSCLKOUT:
If HISPCP
(2)
≠ 0, HSPCLK = SYSCLKOUT/(HISPCP X 2)
If HISPCP = 0, HSPCLK = SYSCLKOUT
000 High speed clock = SYSCLKOUT/1
001 High speed clock = SYSCLKOUT/2 (reset default)
010 High speed clock = SYSCLKOUT/4
011 High speed clock = SYSCLKOUT/6
100 High speed clock = SYSCLKOUT/8
101 High speed clock = SYSCLKOUT/10
110 High speed clock = SYSCLKOUT/12
111 High speed clock = SYSCLKOUT/14

15-3 Reserved Reserved
2-0 LSPCLK These bits configure the low-speed peripheral clock (LSPCLK) rate relative to SYSCLKOUT:
If LOSPCP
(2)
≠ 0, then LSPCLK = SYSCLKOUT/(LOSPCP X 2)
If LOSPCP = 0, then LSPCLK = SYSCLKOUT
000 Low speed clock = SYSCLKOUT/1
001 Low speed clock= SYSCLKOUT/2
010 Low speed clock= SYSCLKOUT/4 (reset default)
011 Low speed clock= SYSCLKOUT/6
100 Low speed clock= SYSCLKOUT/8
101 Low speed clock= SYSCLKOUT/10
110 Low speed clock= SYSCLKOUT/12
111 Low speed clock= SYSCLKOUT/14
