Bit 0 (TCIF):
6.1.17 R10 ~ R3F
These are all 8-bit general-purpose registers.
6.1.18 Bank 1 R5 TC1CR (Timer 1 Control)
Bit 7 (TC1CAP): Software capture control
Bit 6 (TC1S):
Bit 5~Bit 4 (TC1CK1~TC1CK0): Timer/Counter 1 clock source selection
Bit 3 (TC1M):
TC1CK1 TC1CK0

RF can be cleared by instruction but cannot be set.
IOCF is the interrupt mask register.
The result of reading RF is the "logic AND" of RF and IOCF.
