11.2.1
PWCR is an 8-bit write-only register for input clock selection.
Upon reset, PWCR is initialized to H'FE.
Bits 7 to 1—Reserved Bits: Bits 7 to 1 are reserved; they are always read as 1, and cannot be
modified.
Bit 0—Clock Select 0 (PWCR0): B i t 0 sel ect s t h e c l ock suppl i ed to the 14-bi t P WM . This bit is a
